So, I'd been playing Indolent Imperial for MGP, and noticed something a few times. When I go in to take a card whose Ascend bonus brings its side up to 10 or more, it doesn't seem to let me take it with a side that adds up to a higher number. So if I try to take a side that's 7+3 (or even A+1) with a side that's 6+5/6, nothing happens. I'll admit this is usually the final play before the end of the match.

My question is: Are sides with a score of A/10 just automatically invincible, or is this just down to how Ascension is calculated? It's a bit odd that once a side hits a certain value, I just can't take it back regardless of bonus.

I have yet to try this on something that explicitly has an Ace and is unaspected; I'll look into it a bit more and take screenshots if necessary.
