KaiRaego, The Berserker

Mentor Menace Vigilance Trample
KaiRaego must attack each combat if able.
When Kai leaves the battlefield, distribute +1/+1 counters equivalent to Kai's power upon removal amongst remaining creatures under your control.
Creatures that received +1/+1 counters as a result
of Kai's ability have Mentor, Menace, Vigilance,
First strike, and Trample.
At the beginning of your upkeep, if KaiRaego is in
the command zone, create a 0/1 red Human
Disabled Berserker creature token.
