Undith, Spirit Talker

At the beginning of your upkeep, exile a creature
card with from your graveyard. If it has
First Strike, another target creature gains
First Strike until end of turn. The same is true for
a creature card with Deathtouch, Double Strike,
Flying, Haste, Lifelink, Menace, Reach, Trample,
and Vigilance.
