I just thought of a great idea.
What if they were to add a move known as "Second Chance"
A negative priority move, where, let's say a you faint, this move allows you to deliver one more powerful blow before actually fainting.
I.e.
Metagross uses earthquake. Pikachu faints, but because pikachu chose to use second chance,
As pikachu faints It delivers one final blow! and faints right after.
Kind of like the ability Aftermath, except more powerful, same distribution amount, and be an actual move.
I like the way you are thinking but isn't that why they made Final Gambit? I actually don't know. How does final gambit work?
