Dawnglow Infusion
Sorcery
You gain X life if 
was spent to cast this spell and X life if 
was spent to cast this spell. (Do both if was spent.)
Dawnglove bloom is a potent nostrum, but the dawnglow brewed from its sap is nothing less than life itself.

If you spent both and to cast Dawnglow Infusion, you’ll gain (X + X) life. An ability that triggers whenever you gain life will trigger just once.
Whether you choose to spend both and to cast Dawnglow Infusion has no bearing on the value of X. For example, say you decide that X is 4 and you’ll spend on . If you end up spending 
to pay the cost, X is still 4 and you’ve spent both and . You’ll gain a total of 8 life.
This spell cares about what mana was spent to pay its total cost, not just what mana was spent to pay the hybrid mana symbol in its cost.
This spell checks on resolution to see if any mana of the appropriate colors were spent to pay its cost. It doesn’t matter how much mana of that color was spent; the effect isn’t multiplied.
If this spell is copied, the copy will not have had any colors of mana paid for it, no matter what colors were spent on the original spell.
