For the rest of the fight, all of my team mate's cards that were played on the 40x flanking enemy never resolved, and the broken cards just floated in the middle of the screen. It even made it so they couldn't redraw those cards!

If my math is right, the final damage multiplier for this should be 2^40 or 1,099,511,627,776 times damage.

Steps to reproduce this

1. Play Hidden Gem+ and hit Flanking
2. Play Hidden Gem+ and hit Nightmare (or have lots of copies of Nightmare)
3. Draw both gemmed cards, and play Nightmare (replay 3) on Flanking (replay 3) 4 times.
4. Next turn, play entire hand and have your team mate hit the enemy.
