In the case of a completed ability, one could not "go back" or "edit" their selections, correct?
Example, I play Pride before Calamity on my demon in battle, selecting 2 heroes (X = My Redeemed Souls, we'll say 2) to discard. I would not then be able to select 2 more if my opponent played SoG/NJ right?
Pride Before Calamity
Discard up to X Heroes in play. • Identifiers: OT, X = the number of opponent’s Redeemed Souls.
