Modica, Populous Unifier

Eminence — As long as Modica, Populous Unifier is in the command zone or on the battlefield, Human tokens you control are Citizens.
Whenever a non-token, non-Human creature enters the battlefield under your control, up to one Citizen you control gains first strike if that creature has first strike. The same is true for flying, deathtouch, double strike, haste, hexproof, indestructible, lifelink, menace, reach, trample, flanking, and vigilance.
