7 mana for such a game-breaking board swing is just laughable. Make it at least 8, or amplify damage in game by 3, maybe 4
The game’s unplayable and it’s laughable.
P.S. I don’t recall ever seeing someone actually paying 7 mana to play it. I’ve seen it played for 5, 6, but never 7. It was a shock to me when I searched for the card in collection and saw it actually costs 7.
