Chancellor of the Spheres

You may reveal this card from your opening
hand. If you do, for each colored mana symbol in
the mana cost of the first spell you cast this game
you may pay 3 life rather than pay that mana.
When Chancellor of the Spheres enters the
battlefield, you gain 3 life for each color among
permanents you control.
"Witness how the engines of old welcome
the blessings of our unified perfection."
