Wailor, Concerning the wording, I think the second iteration makes the most sense. Concerning the actual card, I like it. I think you did a good job with both flavor and balance. 5 stars.

Demonxz95, Masked Prowler is pretty neat.The wording is a little bit clunky, but I don't know of any way to change that. Stitching Arm is my favorite of the two. Deathstalker Rexxar is probably the most fun Deathknight, and the card also fits  Scholomance very well. I think it might be more balanced at 4 mana, but it is probably fine at 3. 

Linkblade91, I am not sure how balanced this is. If you have Arcane Shot and King Krush then you can deal 14 damage out of nowhere and also have a 8/8 on the board. Mana cheating is generally considered to be not fun, so for the sake of balance and making players less salty, I would change the text to only summon things that cost 5 or less.

TheHoax91, There are 3 types of players in any TCG/CCG: Spike, who wants to win. Timmy, who just wants to goof around. And Johnny, who wants to win in the most creative and/or convoluted way possible. Your card is a card for Johnny, and only Johnny. If that is what you want then keep this idea. But if you want to please more parties then you may consider designing something else.

shaveyou, Basically a Multi-Shot on a stick. I like it. I think it is balanced, and has interesting synergies with other Beast stuff. All around nice card.

Arkasaur, I prefer Ancestral Crescent. Overload Shaman is an archetype I wish had more support beyond big stats stuff like Tunnel Trogg and [Hearthstone Card (Flamewreath faceless) Not Found]. 

grumpymonk, Freezemeister is alright, not terribly exciting, but okay. I personally like the first version of Attentive Student better since it feels more controllable and less chaotic and random. 

BloodMefist, I think the rare version is more powerful than the epic version. I personally like the Heal version better, it just makes more sense to me. If you are playing things like Hellfire or Defile then you are probably playing a control warlock and value healing more than 1/1s. 

anchorm4n, The second iteration of the card is the correct wording. I like the card, though I feel like it makes certain damaging spells too efficient. If you play an Explosive Shot, then the guy in the middle would take 9, the guys adjacent to him would take 7, and the guys adjacent to them would take 2. I would Increase the cost to 3 and/or maybe make it an epic.

Nirast, Sorry, I can't see your card. *edit* There it is! I feel like there is more going on with this card than there needs to be. It all just boils down to a pre-nerfed [Hearthstone Card (fiery war ax) Not Found], except it is an epic, a secret, and has Spellburst. All in all it just feels like a lot of text and triggers for a fairly simple card.

Ekkeh, Having your stuff stolen is never fun. Mind Control is 10 mana and it is still frustrating to have it played against you. This card will probably generate more salt than anything else.

FieselFitz, 3 mana draw 3 is pretty powerful. And when it is attached to a 2/3 with Stealth it is even more powerful. It is a legendary, but it is still a lot of value for just one card.

DavnanKillder, Mad Researcher has a good effect, but is definitely too much as a 2/4. It could be a 2/1 and still be powerful. Trapmaster Alanna is definitely too powerful. Being able to get a full set of secrets for 6 mana and a 3/4 body is just way too much. I think casting random secrets for Spellburst is fine, but maybe if it only cast one secret, cost less, and was a common.

TheHoax91, Neat card. I am not too sure about it since it is a totally unique ability, and therefore hard to evaluate. But I think it's pretty cool, maybe a bit on the powerful side though.

Demonxz95, Personally I like Drown best, though I am not a big fan of the art. Submerged Bomb is pretty good, not terribly interesting, but a solid card. Diving Agent is interesting, it reminds me a bit of Pen Flinger. It seems well balanced and playable.

Wailor, I like Hammerhead Bloodseeker the best. Abyssal Monstrosity is my second favorite. Hammerhead Bloodseeker is probably the most realistic and balanced of your cards, I don't have anything to criticize.

Valor1204, The main problem I have with this card is that now you, a rogue, have to kill all of these 0/2s that are taking up space on your board. If you are playing an aggressive pirate deck you probably don't want to waste resources and space on the board summoning minions that can't deal damage.

Davnan Killder, Undersea Ambush is definitely too cheap for what it does. Nagrand Slam is a 10 mana epic spell. This costs less, and is way more powerful. I think it could cost 7 mana and have overload 1 or 2. Deep Fiend Drowner is interesting. I think that since it is so hard for your opponent to attack it the health should be reduced. Other than that it is fine.

BloodMefist, I think the cost and stat distribution could be a bit better, right now it is half-way between Dragonmaw Sky Stalker and Eccentric Scribe, neither of which are very good. If it had either more base stats or more stats from the deathrattle, and also a keyword then it would be better.

grumpymonk, Naga Fel Witch seems kind of risky. Mana cheating is always going to be dangerous. Oacha'noa is an interesting card. If you can cheat it out in any way shape or form it has the potential to utterly and completely break the game. But, as a vanilla 10-drop it probably isn't the worst thing in the world. 

Arkasaur, I like it. Good flavor, well balanced, good art. 5 stars.

Neoguli, Personally, I never liked the idea of a card that specifically goes to the bottom of your deck. Why would I want to craft a card and stick it in my deck if I was never going to be able to have it in my hand and play it?

MenacingBagel, Roughly 5 mana is usually the cost of killing a minion. This kills 3 minions and the only additional cost is that you have to spend life attacking them. This should definitely cost more mana.

Cg8889, The text seems needlessly complicated for what it does. Why not just have a 5 mana 3/2 that says "Battlecry: Destroy an enemy minion"? Aside from any attack triggers, it would be functionally the same. 

Hordaki, Spending 8 mana to destroy a random enemy seems like a lot. I would reduce the stats and make the battlecry target things. If you are concerned with it taking over huge deathrattle minions you could always have it only be able to target things that cost (X) or less. But making it random only makes players salty.

Pokeniner, I think it should cost 4 mana with 3 attack. A 3 mana 3/3 weapon would be pretty good, and it isn't hard to get a ton of murlocs, making this weapon a 3-mana Blood Fury.

Linkblade91, My main concern is that it's kind of hard to get coins, and even when you do the result isn't that spectacular. I really like the ability, but getting one or two extra Lost Tallstriders doesn't seem like a worth while payoff.

FieselFitz, It seems a bit expensive for what it does. The battlecry version is definitely the best, though I think you should increase the damage to 4.

bgicums, the text should say "Give all minions -2/-2 except for Murlocs".

Grayghost39, This is kind of weird. I think the idea is that on your turn minions are easier to kill, but then go back to normal on your opponents turn. The main issue I have with this is that a 5 mana 4/5 is pretty easy to kill, so half of the time you may not even get the start of turn trigger. 

ChickyChick, Interesting design, but there is no way an 8 mana 5/5 will survive long enough to kill more than 1 minion. If you play it on an empty board then it is incredible, but if your opponent isn't able to play any minions on turn 8 then they probably already lost.
