Anka, doll maker

Whenever Anka, doll maker attacks, target
opponent reveals the top three cards of their
library. Choose a creature card from among them. Create a X/X colorless human creature token.
X is equal to 3 plus the number of creature types the chosen creature has.
If there are no creature cards among the revealed cards, you lose 3 life. The chosen opponent
shuffles their library afterwards.
