Turn 12 - Celesteela clicking Leech Seed instead of Heavy Slam allowed the Ultra Beast to take an extra unnecessary 28% of HP lost to Tapu Fini when going for Heavy Slam is the safer move. Confirmed that Mega Froslass would kill with a Thunderbolt
Turn 14 - Allowing Latias in against Mega Froslass allows Carolina to get rid of Latias, giving Dragonite a safe opportunity to Scale Shot and break down East Coasts team a little easier
Turn 17 - Dragonite Crits Spectrier. If Spectrier was scarfed, surviving a non crit 4 hit scale shot would allow Spec to kill the next turn, and potentially ramp towards a win.
