Loop lands around from hand / battlefield / graveyard.
• Return lands from graveyard to hand or battlefield
• Sacrifice lands as a cost
• Lands that sac themselves; Fetch lands (this is one of my only decks that uses them. I generally don't like fetches due to all the shuffling.)
• Discard lands as a cost. (I looked at Retrace but there aren't many decent in these colors, just Worm Harvest.)
• Lands that cycle (you'll get them back)
• I considered mass land destruction, but honestly the deck doesn't need it, and just makes the deck a target.
