Takeshi, Thorn Among Roses

Whenever Takeshi deals combat damage to a
player, you may have that player gain control
of it. If you do, you may search your library for a planeswalker card, reveal it, and then put it into
your hand.
Infiltrate — As long as Takeshi is under the
control of a player other than it's owner,
whenever you activate a loyalty ability of a planeswalker you control, Takeshi's owner
draws a card.
