I can't really evaluate this.

The effect is pretty damn insane if you hit even just 2 minions, but it's gonna be hard to get off.

5-mana is also quite a heavy cost if you don't have a 0--mana proc at hand.

Fungalmancer this is not.

Probably pretty great in Arena though

all depends on how easy it is to activate frenzy.  goes great for warrior lets see what the others get 

Horrible stats, will need an activator directly or it will probably be killed without activating the effect (most 5 drop have 5 attacks and some 4 drop too). Also need other minions on the board so if the opponent trade the turn before it is nearly useless. Giving +2+2 is not that good in late game. I think this is a bad card who wont see plays.

This one was probably tricky to balance. You need 5 mana + something else to trigger the effect on the same turn, but the payoff is really good. Could it find its way into Token/Zoo decks?

Great arena card.In constructed we need to see more cards that can damage minions .Maybe for zoo warlock?warrior tempo?or tempo deck with the broom?

As long as broom exists, frenzy is looking king of overpowered. This is fungalmancer 2.0 if you can hit frenzy. This is what swarm based boards needed to close the game

Looks great in arena and dude paladin

I do not think this will see much play

Instant pick in Arena

IDK about this one, I wouldn´t play it personally.

Seems a little high costed to me, since it's not an immediate effect.

But time will tell.

Wide board buffs will always at some point be relevant, so I'm not counting this one out yet. Its slow at 5 + a trigger. But the core set has been geared towards tempo so the game is likely slow enough that this card can actually work.

Expect to see some unconventional ways of triggering the frenzy of this card. Maybe rogue, because its the only class that currently has a 0 mana activator in backstab.

if you can drop this on a full board the game is basically over

I can see a Token Warrior, with this plus that 0-mana damage spell.

I can imagine a world where Priest finds a way to use this. Is that world just Arena? Possibly.

can be a better fungalmancer or a simple 5 mana 3/5, probably will see experimentation but I dont think this will be really good

Don't underrestimate this card. It's easy to combo with cards like guardian augmerchant

hard to activate seems like a good arena card

The first set of the year is always filled with potentially good cards. This is one of them, but it's probably too high costed.

I'm not sold on this one, 5 mana plus an extra step to maybe give your minions +2/+2. This is just too expensive and too difficult to use.

this card works well if you have a board

This card might be too slow, but if it can be pulled off then it would be amazing.

Aggro thing?

My sniffysniffer of sniffiness sniffs out a controversial card. Good reviews, bad reviews... I sniff a possible delayed metawarper the likes of Ogremancer. SNIFF!

Personally, she seems interesting but not powerful. Sure, you can whack some crazy combos with it - but most of those combos require specific cards and up the playcost to 6, 7, 8, 9 mana... A 2-card combo on turn 6 that grants you a paltry +2/+2 doesn't seem great, though that additional 'Bloodlust' or 'Murloc Warleader' could be impactful for decks without that win condition, though would any decks curated to go wide have space for several Animated Broomsticks and Guardian Augmerchants...

Yeah, I can see why this card is controversial. Heh.

Frenzy is the first time something survives damage, right? You got a 5 damage spell in hand? Silence? A 5 attack minion on board? I think at 5 health this is going off more than we're giving it credit for. 

Slow, but could be good. 

Rocket Augmerchant Ethereal Augmerchant Guardian Augmerchant will be extremly potent in this meta, with those frenzy effects!

With those Augmerchant cards still around. This could be quite strong on 6 with any board. Might find a home somewhere.

Only actually good with Animated Broomstick or a damage effect like Guardian Augmerchant while you have a wide board. But sadly for this card, there are plenty of other cards that are good with those cards but also good by themselves and without a wide board. So this card won't be worth it.

With any opportunity to give this thing Rush or Windfury, this is going to be a staple in most aggro decks

Great card with enrage warrior

Good board buff, another way to activate it is using the augmerchants, or making it a loser (if you know what I mean)

Pretty interesting, with a trigger this could be really strong.

Should be good in Token decks, but then it is too slow for those... so dunno, doesn't seem good, but can be a fringe thing...

This feels more like like Eager Underling than like Fungalmancer.

The way I evaluate this card is the health for the cost. Can this minion survive for one turn to proc the frenzy? Can my other minions survive? Best case scenario, you want to proc this frenzy on your minions the same turn you play this card. A 2 card combo for a board wide +2/+2 at 5+ mana, seems like a tough ask.

Looks too slow for Constructed token decks. Comes late for aggro (earliest turn 6 to activate, condition to damage it), no immediate impact. Body isn't really relevant without taunt. Not a good card.

There has to be some way to make this work, right? Broom is run everywhere else, I don't see why not a zoo deck.

A pretty strong Frenzy effect, but 5 mana seems a tad difficult to activate when this also requires additional setup.

Broom is a thing, you know? Good card.

Pack filler. Effect is nice, but hard to activate at such a high mana cost. Broom will be a necessity for these Frenzy cards.

so far this was the hardest card for me to rate. effect can be really powerful, but activating frenzy may not be easy. I still dont think swarm decks can play this tho.

I doubt the strong effect is worth the mana cost and mediocre stats of this card.

It's really easy to activate with Animated Broomstick, Guardian Augmerchant, Rocket Augmerchant, for a neutral card it's not that far away from Arbor Up power level.

But with it's more a 6 mana card than a 5 mana card, unless you want to Backstab it or something.

Also a decent Jandice Barov roll I guess

This seems very obviously powerful. The effect lands at a point on the curve where this ability has been historically relevant as an aggro finisher (I'm thinking Quartermaster and Level Up! as two good examples of this), and there are a lot of good neutral cards to activate this with, many of which have already seen lots of play in powerful decks (e.g. Pen Flinger, Guardian Augmerchant, and Animated Broomstick).

Barrens Blacksmith is definitely a card expect to get very sick of seeing very quickly

Great card for zoo decks. If it only had rush...

5 health is enough for Barrens Blacksmith to somewhat reliably survive after attacking something. That thing is, without something like Animated Broomstick to make the admittedly amazing Frenzy effect to trigger, I feel like this card will just be discarded in favor of other easier to activate win more cards because you're spending 5 mana on a 3/5, which is not very impactful, and hoping your opponent either doesn't have an answer to kill Barrens Blacksmith immediatly or he doesn't trade into the rest of the board and force the Frenzy effect to trigger on nothing.

Very nice in a warrior deck prob.

Seems slow in constructed

Arena fodder

Yeah, will agree with the rest of the comments - can be played in Warrior.

Quote From Sirgeekalot

This one seems like it will be fairly easy to proc, with 5 health, chances are good for it to stick and possibly generate the effect twice ? Or maybe I way too optimistic and generous in my rating ¯\_(ツ)_/¯ 

This could be very good in any deck that likes wide boards. I think only rogue will be able to activate it on turn 5 with Backstab. Plenty of 1-mana damage spells though, and if dies but takes 2 hits to kill it, you still get the buff.

Has potential as long as Animated Broomstick and Pen Flinger are in standard to activate its frenzy effect. That said, this might be too slow especially with classes getting multiple AOEs and board control tools. 

Looks too clumsy to me. 5 mana is a lot and then you need to do something extra to trigger its effect. Clearly not impossible, but you would rather be doing something else. This isn't very good in Arena either as this is a win-more card, while generally, comeback cards are a lot better these days.

Arena card. Difficult to trigger, great value is find space in some deck

Nice one for [Hearthstone Card (High Overlord Saurfang) Not Found]

frenzy with no rush are not very good

Mediocre.

Could work in Dude Paladin or Token Decks like Druid oder Zoo - but still seems a little Slow and you also need to activate the Frenzy with a decent board to get a good payoff.

Gadgetstan incoming

Pirate Warrior going places

good card

I think people are sitting on this, I'm a much bigger fan than the average player

Potentially a Fungalmancer, so seeing Barrens Blacksmith did freak me out at first. But it does require you to damage it before you get the buff. Even still getting the Frenzy off should be easy in warrior, and it's strong alongside [Hearthstone Card (High Overlord Saurfang) Not Found] and Warsong Commander. Actually most classes can use this just fine alongside Animated Broomstick. Yeh i think it will some play in aggro/midrange decks.

too expensive to see play

Most of the cards need a lot of setup to work correctly, which means lots of the times, you will sit with mediocre stats, and not being able to trigger your abilities

The buff is nice, but probably too slow

This is a really weird card. What class would play this? Too slow for aggro.

Not sure about the cost and stats but if this sticks it can be very dangerous since they just drop a board with 6 mana. 3/5 will see experimentation I think.

I think this will be a bit too tricky to play. It will just require you have a solid board already and without one its an understatted unit that does nothing. On top of that it doesn't even trigger its effect instantly unless you have something to force it to proc right when you play it. The only class that can damage its own unit instantly without another card being ready is mage and I don't think this will be played there.

Amazing with Overlord Saurfang, but that's it. Likely too sluggish for a token deck.

The thing I love about cards like this is working out ways to play them. 

It seems kind of difficult to trigger this ability. However, I can see it in a targeted frenzy warrior deck. 

In this set aggro gains big pieces, but hard to play! No more brainless games my friend

Insane value with Saurfang

Mediocre, especially in absence of Risky Skipper

Good card with broomstick and other minions to swing the board. Maybe can be find a spot somewhere

I think Alliestrasza judged this card correctly. It seems like it will see play in Warrior, for similar reasons to Quartermaster seeing play in Paladin.

looks weak

expensive, no rush.... too difficult to set off the frenzy without beint killed AND having  board?

Token Druid

Don't subestimate that card, massive buff are dangerous.

Seems a little hard to get to hit the way you want it. Might be workable with some token decks if you can trigger it somehow. 

Good Enough

this + pen flinger = fantastic

Maybe too slow?

quite a strong effect - maybe warrior will try using it? 

good

Too high of a cost, though the effect is really strong.

This is better as a BG minion, where minion-to-minion combat is obviously much more common. I think this is probably too expensive and difficult to trigger to make it into good decks.

Nice buff effect

Nice one with insane effect. Card with huge potential, maybe hard to activate, but f.ex. in taunt warior could be use.

Insane card, hard to remove with all that health. A staple in every deck with Frenzy cards, for sure

Expensive.  Will depend on being able to activate.  Will either see little to no play (my guess), or be activating lethal in a couple of properly constructed decks.   I totally see potential in combo Rogue, but that 5 mana cost makes me wonder.  Maybe token Druid if you run broom?

This seems much too slow and easy to deal with.

High roll this off of the Warrior legendary and that turns into quite the board buff.

not worth it even in combo with Broom

Has potential in a Warrior deck built around Frenzy but I doubt that deck goes wide for this to work. In any other deck it's just too slow.

I think this needs to be used 100% in combination with a cheap activator like Broom or whirlwind, etc. Otherwise, seems like an expensive, slow card.

Could be great on a wide board

Too slow and hard to activate frenzy.

A good effect, but I'm not liking Frenzy as a mechanic. I don't see this making a splash since it's just not worth having to trigger it yourself.

Move over TrumpSC, value town has a new mayor!  With the right board this can be incredible, though with the wrong board it could be terrible.  Maybe this is mostly a win-more card.

Give it rush and it's worth it.

needs a ping to trigger it at the right moment

This looks like a lot of effort to get the board buff in what I assume is an aggressive deck that cares about this effect. Barrens Blacksmith kind of looks miserable compared to Fungalmancer as you can't consistently play Blacksmith and get its effect on turn five.

Maybe a mid range frenzy warrior can shine cuz this.
