I choked by clicking Return instead of Shadow Ball against Scyther turn 50, putting it in Swarm range and preventing me from surviving two HP Bugs. Going Shadow Ball -> Return would have meant you'd need two absolute max rolls on HP Bug to take Kanga out, and it would have come down to how much Speed Missy was running. Probably didn't matter since I wasn't running any Speed on Kanga so if you had 44 EVs or more you outsped me, but it was still a stupid misplay.
