text: Whether you choose to spend both {G} and {W} 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 {G} on {G/W}. If you end up spending {W}{W}{R}{R}{G} to pay the cost, X is still 4 and you’ve spent both {G} and {W}. You’ll gain a total of 8 life.
