when kroxa enters the battlefield, sacrifice it unless it escaped.
whenever kroxa enters the battlefield or attacks, each opponent discards a card, then each opponent who didn't discard a nonland card this way loses 3 life.
escape—bbrr, exile five other cards from your graveyard. (you may cast this card from your graveyard for its escape cost.)
