Grand Zeno, Omni King

Changeling (This card is every creature type.)
As Grand Zeno, Omni King enters the battlefield, choose a creature type.
Spells of the chosen type you cast cost
{w}{u}{b}{r}{g} less to cast. This effect reduces only
the amount of colored mana you pay.
Other creatures you control of the choen
type get +1/+1.
