Janko, Junkmaster Savant

Whenever a creature you control deals combat
damage to a player, create a token that's a copy
of target noncreature token.
Sacrifice four noncreature tokens: Exile cards
from the top of target player's library until you
reveal a non-and permanent card, then put
that card onto the battlefield.
