Gujaga, Bear Witness

All creature cards are bears — not the
creature type, but the creature architype.
(All creature cards have mana cost 2, however
that requires their cost be reduced, starting with
colorless mana and descending in WUBRG
order. Mana costs lower than 2 are increased by
generic mana, and any costs that include X lose
all non {x} costs, and X becomes 2. All creature
cards are 2/2s.)
