Most decks I play can't get much value out of Stomp. If you've already played three attacks this turn, do you really need to play this one as well? It would probably be better to put better attacks into your deck, such that playing three of them in a turn killed the enemies already.
Keep an eye out for spots where it's genuinely good though. A Flash of Steel, Pommel Strike, and Anger early + a Battle Trance could make this a very appealing card.
A very nice pickup to help with multi-enemy fights. You can pay full price if you really need to, but goes best with some 0-cost attacks to make it cheaper.
At the end of your turn, 1 random Attack in your Hand is played against a random enemy.
Exhaust your Hand. Add 1 random card into your Hand for each card Exhausted.
Deal 12 damage to ALL enemies. Costs 1 less for each Attack played this turn.
