The base power and toughness of all creatures on the battlefield is X, where X is that creatures converted mana cost.
At the beginning of each opponents precombat main phase, if they do not control a creature named either Scornful Egotist or Scornful Egotist Sympathizer, add {u}{u}{u} to that players mana pool.
This creatures base power and toughness is completely irrelevant!
