Thraben Watcher

Anthem effects usually stop at the numbers; this one attaches a keyword to the buff, and the vigilance grant rewrites how the board plays. Every other nontoken creature you control can attack without tapping down, which dissolves the standard tension between pressing damage and keeping blockers back. A white army assembled from individually cast bodies can push through and still present a full wall on the crackback, denying the punishment a go-wide deck normally invites. The nontoken restriction is what aims the effect: token swarms, the obvious home for a +1/+1-to-everything buff, get nothing here, so the payoff belongs to weenie builds already deploying creatures one at a time. That pins the reward to boards of small permanents rather than a swarm conjured by a single spell, and it favors the slower, grindier flavor of going wide. As a 2/2 flier for four, the body trades poorly against most creatures at its cost; what matters is the eight or ten nontoken creatures standing beside it, each turned into a vigilant attacker that can race and defend at once.
