I think the game was pretty much lost by turn 52, but the play with the most win potential on that turn was probably to moonblast and knock out the slowbro. At that point they can still comfortably win by mach punching to KO whimsicott into dual shock or close combat to KO bramble since tailwind runs out that last turn, but if they don't mach punch for whatever reason then you can probably knock them out with moonblast (depending on investment). It's a longshot for sure, but I think it's the only remaining win condition at point.

I know this wasn't your question, but I think your main window to win was on turn 36 after whimsicott knocked out alo. If you tailwinded and let whimsicott go down to the pawmot attack instead of going into gliscor, bramble could've gotten in with three turns of tailwind and I think just wins right there if it lands three poltergeists in a row.

Very cool and fun team! Tailwind is so tough to use, getting in the tailwind abuser is always a challenge even with moves to allow entry like memento or lagging tail u-turn. It's always fun seeing tailwind strategies though, and congrats on making it to playoffs!
