KH2FM+ CM - Volcanic and Blizzard Lords

Annoying, and also easy. Not much strategy needed, just skill/practice. I lacked a little of both in this fight.
Do one of their RC, kill the spawns, RC the other, kill their spawn, loop. I don't really have much to say about this fight. If you always watch the Lords, your fine.
