I honestly don't understand why druid keeps getting ways to combo. (as you can see, I don't like otk combo decks)
Nevertheless, this is a really good card.

I don't know why they would print something like this, but screw it, it's combo time I guess.

I'd like to point out the very VERY concerning potential with Ysiel Windsinger. Basically all you need to do is have both in hand and playing two Invalid Deck ID. No matter how they land you are now able to get out both Ysiel at the same time, then play any spell and have 10-mana to cycle through your deck and play every high cost spell under the sun.

Now maybe that's not too scary right now but it basically improves every single high-cost spell they print until this year rotates from standard.

Sure, we don'T have a real OTK with this, but just think something as silly as The Forest's Aid + Soul of the Forest, + the 10-mana buff spell (or any other permanent buffs) while also cycling through your deck via Overflow.

We're talking about a 4-card base combo that allows you to get through your entire deck while being able to set it up throughout the game without too much of a tempo loss.

Another combo card for Druid that’s probably gonna get nerfed somewhere down the line. 

If you play this at t6 and cast the new [old] Innervate, you will get 8 extra mana or just 6?

By the way, a really good card.

I mean...that's a card. Seems really easy to have a combo deck with this discounted with Imprisoned Satyr. 

Discount Forest Warden Omu to 1 mana or Malygos to 4 mana.

Turn 10, play Omu + Malygos + Moonfire x2 + Swipe x2 + for 30 damage. 

Not like Druids lack card draw. Seems like this could be a 5 star card for combo Druid.

Not sure if you run this in other versions of Druid. Big Druid doesn't want to play a 6 mana 5/4 (would be great to get off Strength in Numbers to reset your mana but that seems to be niche use). Spell Druid could use it to reset mana with Exotic Mountseller but that deck already has enough mana due to the 0 cost spells to fill your board.

Not actually sure how much better this is than kun, given that aviana is usually a component of druid combos. Maybe this gives those decks a hit of consistency that they were needing. This is obviously good somewhere, but I don't exactly know where.

for it's cost this minions stats are pretty modest. 

HOWEVER - REFRESHING YOUR MANA CRYSTALS IS PRETTY STRONG.

Druid historically loves to utilize their spells for either combos or to buff their minions.

In AoO Spell Druid adopted Exotic Mount Seller and Kael'Thas Sunstrider as their only minions, despite having  Ysiel who makes spells cost (1) mana as one of their class legendaries from the set. Ysiel saw no play as she was incredibly expensive, and Spell druid was using the reduced cost bogbeam and Ironbark spells to help Kael'Thas cast an expensive spell for free or Exotic Mount Seller to flood the board. Ysiel, despite her cost reduction was actually anti-synergy with the current plan for druids.

Omu however is a different story - while his stats are modest for his cost, being able to refresh your mana crystals to give you essentially an extra turn is a massive play. The World Twig from KaC was often used as this, and there's been times when an adventure was won with the Druid class because you refreshed your mana crystals in one form or another.

For Druids this means another way to pull off combos with Malygos. Forum member Trimutius has mentioned a combo with placing this minion on the board, refreshing your mana crystals, using Maiev Shadowsong on him so he's dormant and can't be interacted with, and once he's available you can slap Malygos down and use the standard moonfire, swipe, swipe, moonfire combo for lethal. Although you could also probably use germination in that combo if you had to use a swipe for board clear 

Ysiel may also see play with Omu, since they have a very, very soft synergy. You can play Omu, play say innervate, then play Ysiel, and then you can play high cost cards like Survivial of the fittest, making the two minions 9/8 and 9/9 respectively. But you'll probably want to discount them with Imprisoned Satyr or Jepetto Joybuzz to get the most of that combo 

Cool card.  Not just for a big combo style deck but any deck that is playing cheap spells can run this.  if you're going to play a cheap spell then you can basically just play this for free.  

Kun 2: electric boogaloo.

on a more serious note, Druid doesn’t need help for combos in wild. This just makes the deck more consistent

Orgasms in druid

I am already angry that quest mage can generate 3 turns in a row in wild.  With the new cards is seems druid might be able to generate about 5 turns worth of mana.

Yet another combo tool for Druid. Seems good, also kind of boring.

In most cases this would just be a 5/4 for free. Is that good enough? Usually yes, but for druid this is perhaps not what they need.

There's obviously some set up with this card. But I don't think it will make the inclusion into OTK decks. If you see this in high levels in standard at all, chances are its because its a 5/4 for free.

Good grief, again with the mana refresh.  If not now, then at some point in this game's history this card will be heavily abuseable.  I can't think of any particular combos that can be done with this, but this enable Druid to get some pretty big swing turns by essentially developing a 0-mana 5/4 along with some other card after you play one of Druid's many low cost spells.

It will be part of at least one combo deck at some point in time. I don't know if it will be good or not, but this card will be a part of it.

Honestly, if you think about it, Druid was already a combo class, although their comboes relied on huge board swings. Whether this card can make said combos become more OTK focused remains to be seen. Still scary though.

Outside of a combo I can't see this card seeing play so there's either an OTK that this card enables or it's pointless.

Forest Warden Omu looks scary. Playing it with Germination gives you 10 free mana instead of 4 free mana on 10 mana crystals. This allows for combo potential with Malygos, especially if Malygos is discounted by Imprisoned Satyr which would allow for Malygos to be copied and have 10 mana left to cast spells at your opponent's face. The extra Malygos isn't even necessary if you set your opponent to 15 with Alexstrasza the turn before.

There is a natural check for Maly Druid if it becomes competitively viable: it is weak to tempo/aggro, which has made up most of the past 2 expansions' metas. I don't imagine a Maly Druid being higher than a tier 2 deck in Scholomance.

Druid and all those mana cheating mechanics, with all those 0-mana-after-turn-7 spells this will be trivial. Now we just have to find a combo worth playing.

I honestly had the same reaction to it .. ''Yeah .. an other combo pieces for Druid WTF'' ..
In case the class identity wasn't clear enough, we now get a reminder

Well i think this is a good card - most of the time this will be a 5/4 for free because you can easily play it with a spell (lots of 0 Mana spell in druid) so i would say this is pretty darn good!

If your Malygos is already discounted then You don’t really need to bother Germinating Forest Warden Omu to set off the combo... just play Malygos and spam..

Combo decks are very much part of Druid’s play style.

In standard this looks decent.. it's basicly a free 5/4. (+4 mana -cost of whatever spell you casted)

In wild: NOOOOOOOO. Kun the Forgotten King and Twig of the World Tree have similar effects, and have always seen play in OTK druid. This deck will also run this so they can do the combo more reliably.

I honestly think this won't have an impact in wild, maybe if OTK druid was good this would push it too far, but it's not good. As for standard, this is THE card that will make OTK druid a thing, but no matter how "broken" it may seem, it can only really be good if the meta isn't aggro which I doubt will happen.

Pretty good mana cheater. Definitely combo potential here for someone to discover.

I just know that wild decks are going to mix this, Twig of the World Tree, and K[Hearthstone Card (un the Forgotten King) Not Found] together for some mana ramp combos I really hate, lol.

So, possible 3 cards combo, to then steamroll the game: Turn 10Forest Warden Omu, then any spell, than Fluffy Fight. A 7-10 Mana combo which leaves a 9/8 on board.

Blizzard - "We learned from our mistakes"; prints Forest Warden Omu.

This card will end up breaking the game at some point, mark my words. 

Don't know how this'll do in Standard, but I doubt that we'll see much of this in Wild. Aviana/Kun the Forgotten King Combos already have more Mana than they need. Forest Warden Omu would be just a Win-More Card in those Decks.

This card can "broke" the game. A super combo is with Germination and you can easly set a OTK. Malygos is around the corner...and with the ramp ability Forest Warden Omu can be a problem in the next future

No more wild Druid mana regenerating please!!

I do not think it is as powerfull as people think it is...

This can just cheat so much mana right now....Insane

This card is amazing lol, Kun 2.0.

Amazing Card cant wait to see what combos people pull off

Druid is probably going to do some disgusting things with this one.

The combo with Germination is absurd in any type of Malygos or Big spell (Survival of the Fittest) druid deck.

Ridiculously strong card. I suspect this to be a staple in standard and wild for quite some time.

Combo enabler and tempo/swing plays possible make it sure it will find some kind of home, especially since it is playable in the mid-game.

We love a vers Queen!

Very powerful OTK card.

Powerful effect but a little boring to be honest. It enables combos and swing turns but we have seen this effect before in Druid.

Useful only if you can ramp like crazy, and just barely. Wasted legendary slot for me.

Combo is back baby! (Till opponent plays Mindrender Illucia and ruins your combo)

I cannot see a deck for this one

Got the golden version in my packs. :')

It will enable some degenarate combos, as his cousin Kun the Forgotten King did

Yeah... I look forward to getting absolutely wrecked by this card's effect in the future.

Oh, Druid. Soon you'll be able to summon a full board and destroy 30HP at turn one.

Crazy effect on this card. This will most surely be put to use in creating some sort of OTK.

My brain isn't big enough to come up with the combo that breaks this card. Somebody figure it out for me so I can feel smart when I use it to get to like, Rank 10? Wait, we don't use those anymore, do we? Gold, then.
