I have to get approval to make an LC showcase thread, i keep forgetting to do that.
for the first team earth power>ancient on amaura, and hyper voice is better than nature 95% of the time
on the second team i'd say aftermath is more relable than static on volty, swapping riolu's or anorith's SD for another move might be beneficial, i'd say use aqua jet if swaping out the anorith, and crunch, shadow claw or P-jab is swapping w/ riolu. on lotad HP electric is useless since it has moves that hit fliers already, and gets wrecked by fletch anyways, maybe use sub?
on the third team a sturdy juice recycle magnemite would perfectly fit, the only thing to watch out for that i can specifically think of is pancham, which breaks trubbish w/ no chance of fixing.
