Alright Skarmory, time to catch our breath, Fly on top of the pillar the flame was blown out, and then sit there, catch a breath, Charizard can't keep that shield up forever. Then use Swift to weaken his shield, and finally, we want to stay awake and alert, so take another turn to rest. If Charizard attacks you during this final turn, use Detect.

fly up to pillar with no flame on it, and wait, Swift, Wait/Detect.
