A cycle of common, mono-colour-producing lands that enter tapped but provide a small effect when they do.
Sandstone Bridge ( W ) - Target creature gets +1/+1 and vigilance until end of turn.
Skyline Cascade ( U ) - Target creature an opponent controls doesn't untap during its controller's next untap step.
Mortuary Mire ( B ) - Put target creature from your graveyard on top of your library.
Looming Spires ( R ) - Target creature gets +1/+1 and first strike until end of turn.
Fertile Thicket ( G ) - Look at the top 5 cards of your library. Reveal a basic land among them, put it on the top of your library, and the rest on the bottom.
