Infeareal Flagbearer

While an opponent is choosing targets as part
of casting a spell they control or activating an
ability they control, that player must choose
at least one Flagbearer on the battlefield if able.
Nightfall: 2 target Zombies get +1/+1 until end
of turn Whenever a Swamp or mono-Black
creature enters the battlefield under your control
Imperial soldiers fondly wish the Infeareals were
so dumb the flagbearer didn't matter.
