Just had a pretty lolz ragequit scenario (which also means no video :( ). I can't remember which Pokemon he sent out first, but it ended up as Mawile and Ditto on my side versus Kangaskhan and Cloyster on his. It went something along the lines of this:
Scenario: Mega Mawile vs Kangaskhan, both on full HP
Kangaskhan mega-evolves and uses Power-Up Punch; the two hits take off about 1/3 of Mega Mawile's HP
Mega Mawile uses Play Rough; again, this takes off about 1/3 of Mega Kangaskhan's HP, so this must be a pretty defensive Kanga
Mega Kangaskhan uses Earthquake
Mega Mawile faints
I send out Ditto
Imposter triggers, and Ditto transforms into Mega Kangaskhan (with its two Attack boosts from Power-Up Punch)
Ditto uses Sucker Punch; Kanga is left on 1/4 HP
Mega Kangaskhan uses Sucker Punch; the move fails
Ditto uses Sucker Punch
Mega Kangaskhan faints
He sends out Cloyster
Ditto uses Sucker Punch; the move fails (i'm locked into it because of Choice Scarf :( )
Cloyster uses Shell Smash
Ditto uses Sucker Punch; this takes off 2/3 of Cloyster's HP
Cloyster uses Ice Shard; this does very little damage (i guess he thought Ice Shard might go first)
Ditto uses Sucker Punch; the move fails (i now have 0 PP left)
Cloyster uses Shell Smash
Cloyster uses Shell Smash (getting a bit cocky)
Ditto uses Struggle
Cloyster faints
Cue ragequit.
