Bruce, Archmage of Chaos

At the beginning of your upkeep, choose a color.
Until the beginning of your next turn, spells, permanents, and cards you own are the chosen
color and lands you control tap for the chosen
color in addition to their other colors.
{w}{u}{b}{r}{g}: Shuffle your library, then exile the
top card. Until end of turn, you may play a card
from exile, from your hand, or from your
graveyard without paying its mana cost.
