Everything in the Devour for Power Commander deck: all 100 cards with current prices, what the deck is worth against the sealed price, the 15 new cards, and whether it is worth buying.
As The Mimeoplasm enters, you may exile two creature cards from graveyards. If you do, it enters as a copy of one of those cards with a number of additional +1/+1 counters on it equal to the power of the other card.
At today's prices the singles come to $120.61, carried by Grave Pact ($30.62), Riddlekeeper ($10.02), Memory Erosion ($7.40). 15 of the 100 cards are new to this deck. Draftsim's Commander 2011 review covers whether it is worth the sticker price.
