Land-Plains Island (Rare)

(Tap: Add W or U to your mana pool.)

When Forbidding Aqueduct enters the battlefield, return a land you control to its owner's hand.

W, Tap: Target blocking creature gets +0/+1 until end of turn.

1, Tap: Target land becomes a 2/2 blue Cephalid creature until end of turn. It's still a land.
