What is the exact timing of "you may do both?" on cards like Growth Through Sacrifice?
It's checked at the moment you need to know, so as soon as you must choose A ~or~ B.
For Growth Through Sacrifice, you check the threshold as soon as you face the choice between "add a Presence" and "remove a Blight" (to see if you can do both). If you don't have 2 Sun at that point, it doesn't matter if you get 2 Sun by adding a Presence, the time for checking "can you do both?" has passed. (Note that the ordering of the two options is irrelevant to this.)
For Unleash a Torrent of the Self's Own Essence, the choice comes at the very start of the card, so if you have the threshold at that point, you still get to do both even if Forgetting a card (from play) for the first option drops you below the threshold for the 2nd option.
