Midoriya

Trample, Haste
Whenever you activate an ability of a planeswalker, Midoriya gains +3 +3 until end of turn.
When Midoriya deals damage to any target, put a +1 +1 counter on Midoriya.
If a planeswalker leaves the battlefield when Midoriya is under your control, draw a card and deal 2 damage to any target.
