Zaraki Kenpachi, the Undying

Indestructible, trample

Zaraki Kenpachi cannot block and attacks each turn
if able.

At the beginning of your upkeep, if an opponent controls a creature with greater power than Zaraki Kenpachi, Zaraki Kenpachi gets +10/+0 until end
of turn and fights that creature. If that creature does
not die, tap Zaraki Kenpachi.
