Saltcrusted Scrub
Land-Plains Swamp (Rare)

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

Saltcrusted Scrub enters the battlefield tapped unless you control three or more Knights Clerics.

1W: Saltcrusted Scrub becomes a 0/4 white and black Cleric creature with defender until end of turn. It's still a land.
