Abilities: Vanilla Creatures

No one can say that a creature without abilities should be part of the discussion on abilities, but for the sake of completion, in an abilities discussion we must mention those creatures that do not have any abilities, the vanilla creatures. Although we often associate junk commons with vanilla creatures, if a vanilla creature has a high power/toughness relative to its converted mana cost, it will be useful. These three are solidly in the junk common category. 2*CMC > P + T for all three. For Thraben Purebloods we have 10 > 8; for Fortress Crab 8 > 7; and for Rotting Fensnake 8 > 6.
