Thanks a lot mate. Coult you explain a bit how to work with those movepools? Which move I would use first...
For the Dragon Dance sets (Charizard, Altaria, Dragonite), generally you set up a Dragon Dance or two before you go for a sweep. For the bulky Dragon Dance Altaria, you have the bulk and recovery to get away with setting up more than twice before you go for a sweep.
For Substitute Mega Sceptile, you set up a Substitute on a predicted switch or a predicted status move, then attack accordingly.
