Zuko, Redeemed Prince

Haste, First Strike
Firebending Mastery — Whenever Zuko attacks, he deals 4 damage divided as you choose among any number of targets. Creatures dealt damage this way can't block this turn.
Path to Redemption — Whenever a creature or planeswalker an opponent controls dies, if it was dealt damage by Zuko this turn, exile it. Then put two +1/+1 counters on Zuko.
