Well im pretty sure that Toxic is gonna drain me before i can Get the job done but that doenst mean we wont go down Fighting.
Ok Charmander, that bug is gonna have to waste a turn doing something to get out of the Firespin so lets hit it hard and Fast.
First use Sunny Day then hit it with a FireBlast and end the round with a Slash attack!

Sunny Day - FireBlast - Slash
