Stealthy Thopter

Flying, skulk
When this card is crewed, remove all cards
crewing it. Then search your library for up
to 4 creature cards. Put them onto the
battlefield facedown as blue 2/2 Human
creatures with skulk crewing this creature.
Return them to your hand at the beginning
of your end step. Activate only once per turn.
This card's power equals the power of the
facedown side of those creature cards combined.
