When Writheling enters the battlefield, exile up to one target card in a graveyard. If you do, each opponent loses 1 life and you gain 1 life. When Writheling leaves your graveyard, draw a card.
As long as it's your turn, Yaeji has first strike. Whenever you amp it up, exile up to one target permanent card with mana value 3 or less from your graveyard, then create a token that's a copy of it.
