Stat boost (Agility/Recover advised)
Spore to sleep your opponent so you can boost your stats with the stat boost moves. Spore when you predict your opponent to wake up or has woken up (if you outpace them). If your opponent hits you, activating the focus sash or they will KO you next turn, use baton pass to pass your stat boosts on. Agility is advised, as if your opponent is faster than you, they will KO you. If you are slower than your opponent, switch out so you stay safe. You can use recover to heal yourself from the damage taken while your opponent is asleep.
