Malekai, Collective Fury

At the beginning of each combat, Humans you
control gain first strike until end of turn if you
control a creature with first strike. The same is
true for deathtouch, double strike, flying, haste,
hexproof, indestructible, lifelink, menace, reach,
trample, and vigilance.
Camaraderie (Whenever you cast a Human spell,
this creature gets +1/+1 until end of turn.)
