1 Mana(Resource) for 7 cars? what deck should not have 4 peace of this?
Answer, every deck should have 4 of this
Be sure to play it in the opponents draw step, first turn, to ruin his "Mulligan" and you have card advantage at worst.
That is if your deck cant win with 7 cards on the spot :D
Its powerful with rush decks, combo decks.
Downside the opponent draws 7 cards to so? (if you win in this turn it matters little.)
Best card of the game by far.
