Azu, Pantheon's Pinnacle

Your devotion to any one color or combination
of colors is equal to your devotion to all colors
instead.
You may spend mana as though it were mana of
any color.
Converge — Whenever you cast a spell, scry X,
where X is the number of colors of mana spent
to cast that spell. If all five colors were spent to
cast it, draw a card.
