That is ridiculous.
If the effect had been a battlecry ( and thus only for one turn ), it would still have been an amazing card.
If the effect occurs on every friendly turn, the card is insane and probably would be auto-included in a ton of decks.
If the effect occurs on every turn, both enemy and friendly, the card is absolutely the most OP thing in the game.
You won't have to worry about efficiently trading at all; your dead minions come back anyway. Play this while you have a taunt up and the opponent can't touch you. Play Faceless Manipulator on it and your opponent can't do shit because they'll have to kill both in the same turn.
Freeze Mage : Kel'Thuzad + Mirror Image + Mirror Image = GG.
You think Molten Giant + Molten Giant + Defender of Argus is bad?
Molten Giant + Molten Giant + Sunfury Protector + Kel'Thuzad. You'll need to kill the taunted giants first, but if you then can't deal with another 8 health creature, those giants will come back at the end of the turn and your opponent will have 22 damage on the board.
Any deck that can flood the board is essentially getting a massive buff here.
Classes without decent removal spells won't stand a chance.
And what the hell are you going to do vs. that Rogue deck that plays stealth on it the next turn?
Maybe Priest will now get some more play with Dark Cultist and Mass Dispel, but then there's that 5 Mana 4/7 creature that they can't deal with.
I'm hoping it's fake ( and it might be because it's a blurry picture of a screen taken at an angle ).
