Steadfast Crew

Whenever a creature enters the battlefield
under an opponent's control, you may untap
Steadfast Crew. If you do, it gets +1/+1 until
end of turn.
"The crew never wavers in the face of the
enemy. After that kraken, they firmly believe
that Annabelle will lead us through any battle,
no matter the foe." - Meredith Seaworth
