In the past few years, Magic designers have avoided creating "block monsters," which are synergy packages that exist within a set
Its a hopeful card that would only benefit from a greater playability from Altaria ex (as it stands, the card isnt competitively viable)
Whenever this land or another land you control enters, if you control seven or more lands with different names, create a 2/2 black Zombie creature token
Im not sure which cards will break out of this most recent edition (early bets are on Ajani, Nacatl Pariah and Necrodominance), but by juicing new cards so much, I fear that old favorites may soon wither away
This set has enough elves that this is actually a reasonable playable in most Green decks
Outside of a heavy tribal slant or some other design parameter disqualification, I cant see a reason why a Cube with support for black aggressive decks wouldnt want this card
