Erwin, Leader of Humanity

At the beginning of each combat, creatures you
control gain first strike until end of turn if
a creature you control has first strike.
The same is true for flying, deathtouch,
double strike, haste, hexproof, indestructible,
lifelink, menace, reach, skulk, trample,
and vigilance.
— (Alter of Odric, Lunarch Marshal)
