Cast:
Rarity:	R
Collector #:	138
If Mox Diamond would enter the battlefield, you may discard a land card instead. If you do, put Mox Diamond onto the battlefield. If you don't, put it into its owner's graveyard. : Add one mana of any color.
Pro Tip! Maybe Mox Diamond isn't as powerful as its older siblings, but it rightly belongs in the Mox family. It powers out fast starts, fixes mana colors, and when paired with cards like Life from the Loam, it has basically no drawback.
