Pool of Omens

Comes into play tapped
When a Teoyt creature enters the battlefield, scry 1
{t}: add {g/u},{g/w}, or {w/u} to your mana pool
{t}, {1}: Scry 1, then draw a card, shuffle this
card into your library
When Coyt magic manifests, one may see the future, but the future beyond that then changes.
