As as additional cost to play Convulsions from the Bellows of Hell, banish 3 random cards from your graveyard.
If a card with 6 or more [Power] is banished this way, the next attack action card you play this turn gains +1 [Power] and dominate. (The defending hero can't defend the attack with more than 1 card from their hand.)
Go again
