Dyramak, of Void and All

When a multi-colored permanent enters the battlefield under your control, add {c}
{w}{u}{b}{r}{g}, {t}: If you control more
multi-colored than colorless permanents, draw a
card for each and gain life equal to the number of colored mana symbols in their mana costs. Otherwise, colorless spells cost {1}{c}{c} less to cast
until end of turn. Colorless creatures you control
get +X/+X where X is the number of colorless
mana symbols in their mana costs
