So this list is not perfect. In fact, I came up with it in about 5 minutes so I'm sure there are things I overlooked. However, the general idea is here. The goal is to get two Golisopod-GX on the field with a Rainbow Energy on both of them so I can free retreat them every turn with Manaphy-EX's ability. The promo Lurantis is there to turn 2HKOs into OHKOs. I have lots of switch options even if I can't rely on Manaphy-EX. 3 Guzma, 3 Tapu Lele to grab them for consistency, 2 Escape Rope, 2 Float Stone, and Puzzle of Time to get back whatever I need. My biggest concern is the fact that this build has 22 Items with Garbodor running around. Overall, I like the list though and would like feedback because I want to try running this once Burning Shadows is released.
