Flat Tubes
Land (Rare)

Flat Tubes enters the battlefield tapped unless you control five or more artifact lands.

Tap: Add WB to your mana pool. Flat Tubes doesn't untap during your next untap step.

Morph WB (You may cast this face down as a 2/2 creature for 3. Turn it face up any time for its morph cost.)
