Storm. (Followers with Storm can attack enemy followers and leaders on the turn they're put onto your field.)
Strike - Each opponent buries the top card of their deck. Then, if there are at least 10 cards in opponents' cemeteries, give this follower +2.
QIf my opponent's deck is empty, and I make them put the top card of their deck into their cemetery, do I win the game?
ANo. If you draw a card when your deck is empty, you lose the game. If you put the top card of your deck into your cemetery when your deck is empty, nothing happens.
