Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
MMM... I think you haven't applied Technician to my Water Pulses, which make Hippo take +9 damage, that should also apply to other attacks on this battle, but I'll leave it like that
"Ok let's finish that little duo"
Isis: Fake Out (Hippo) ~ Water Pulse (Hippo) ~ Chill Fantine: Chill ~ Hex (Hippo) ~ Torment (Nohface)
Isis: Flamethrower (Nohface) ~ Flamethrower (Nohface) ~ Flamethrower (Nohface) *If Nohface uses Dig then switch targets to Cacnea Fantine: Thunder Wave (Cacnea) ~ Blizzard ~ Blizzard *If Nohface uses Fake Out on you A1 then push actions unless Cacnea has a Substitute or clones A2
