So I start off with the Aron, get the opponent's HP to 1 with Endeavor, while getting back to full health with the shell bell. Then during my next turn, I switch to Mienshao, who will take some damage, but recovers 1/16 Max HP after that turn ends because of the Leftovers, then again after using Protect. Finally I use U-Turn, to kill off that 1 HP, while switching back out to Aron, which restores 1/3 of its Max HP. So that combo works pretty well, because for the most part, Mienshao can stay alive because of the Leftovers and Regenerator Ability. If something happens to it, I can still use Aron usually to get the next Pokémon's Health to 1, and then he's pretty much useless. So instead I have the Landorus to provide hard-core backup. With Calm Mind to raise Sp. Atk/Def., it has Earth Power, Sludge Bomb, and Psychic. Sheer Force takes away the additional effects, (like poisoning the Pokemon and lowering its Sp. Def) and instead gives the move a 30% boost. Then the Life Orb, for whatever reason, loses its HP recoil, but still adds the 30% boost, when combined with Sheer Force ability. So Landorus is 60% more powerful.
I'd love and advice or comments or whatever - just tell me what you think! :)
