I just managed to play a few games of Momir basic today, and it got me thinking about what creatures were top of the list for the cmc. For all who don't play it Momir basic is an online format with a 60 card deck of basic Lands and a {Momir Vig, Simic Visionary} card from vanguard. The format is awesome and quite hilarious sometimes.
"From vanguard"?
Vanguard was a different format of mtg.
