Scout Commander Kerrigan

At the beginning of each combat, Scout and Beast 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, feral, trample, and vigilance.
Whenever a Scout or Beast creature enters the battlefield, target Scout creature gets +2/+2
until end of turn.
