This would be even better if it didn't damage demons like how Dragonfire Potion doesn't damage dragons, but I guess you can't expect too much from a warlock class card.

LITERALLY WILDFIRE

After encountering this card for like a gazillion times in Arena, I've come to the conclusion that this card (in conjunction with abyssal enforcer + blastcrystal potion) is really, really strong. Because of these 3 cards, Warlock seems to be the strongest class by far in Arena. Although I'm not a strong supporter of nerfing cards, I do however feel that the current Arena meta is a bit unbalanced in the favour of Warlock. And although other classes tend to have some strong cards as well, I think the synergy between (one or multiple) abyssal enforcers and (one or even multiple) felfire potions is just too good, and you often feel like you couldn't have done anything different when you lose on turn 8 to a felfire potion to your face after your opponent played an abyssal enforcer the turn before and was able to attack your face with it. Of course this specific situation might not occur everytime you come across (or play as) a Warlock, but I'm trying to be an infinite arena player and in my last 30 games versus a warlock this has happened to me at least 10-15 times (and I've played the combo myself for at least 5 times in my last 20 games as a warlock). It's 15 damage + two board clears over two turns, and it's a combo that you can hardly play around/do anything against. So, at this time of writing, Warlock is in my opinion a bit too strong compared to the other arena classes, and you might say it's a bit overpowered. I personally think it would be a lot better if Blizzard 'nerfed' one of these cards (abyssal enforcer + felfire potion) for arena, because in conjunction they are just too OP in my opinion. Warlock already has a lot of good class cards, and one of the best Hero powers, so they really don't need both these 2 cards in my opinion to still be a great, if not still the best, arena class.

To bad warlock loses their healing

When Reno dies this card will die because of the self damage

While I should be happy, I'm so annoyed by the fact Warlock has like million spells that destroy/deal damage to whole board while classes like Rogue are still just playing Fan of Knives <.<

They recently added even more health buffs to Priest in the form of Kabal Talonpriest, while Mage still has basically nothing in that area.

Different classes are good at different things. From Twisting Nether and Shadowflame being in the classic set, I can gather that the devs always wanted Warlock to be very powerful when it comes to board wipes; now they're just adding more, better tools to reinforce it. Rogue tends to win through draw-heavy combos, not long control games.

Doesn't add much for board clears for Warlock, he already got many all characters/minions AoE, if this didn't hit demons or something like that might be worthwhile.

Wow this expansion has Boardwipes written all over it.

This is a rare, holy shit arena locks might play control instead of just zoo with the new Abyssal Enforcer being a common. Maybe for once it's clear the board yes SMOrc No.

Nice, just need a few more cards and control warlock decks might be worth a damn again.

Woahh Wildfire ! I'm going to burn my enemies like a lannister .

BURN BABY BURN! 

6-Mana Ysera Awakens, which is a really good card. Nice!

i didn't know harambe play hearthstone :D

Because Shadowflame needs another minion. Shadowflame + Cho'gall needs Cho'gall and you must include him in your deck.

This card is much better in Renolock because it's an HUGE AoE that doesn't need any setup. The downside obviously is the 5 damage to you but you're comparing this to Shadowflame + Cho'gall which hurts you for 4, which is the same thing after all. The effect and the fact that it's a single card and not a combo, makes it far more stronger than Shadowflame.

Why not play both? In a Reno deck I imagine having another big aoe adds consistency, does it not?

I would 100% play this over Twisting Nether. It's too slow and ineffective against a lot of deathrattle minions, namely in Hunter. Obviously most board clears are ineffective against deathrattles, but having 2 extra mana lets you at least have a chance to finish them off.
