This Grass core can wall out a large majority of the team with Mega Venusaur+Ferrothorn, and remove the threat of Mega Gardevoir with Scarf Tapu Bulu. Starting with Mega Venusaur, everything not named Klefki gets 2HKOed or straight up OHKOed by Sludge Bomb, and Klefki without Twave is super easy to 1v1 with Leech Seed+Hidden Power Fire. It can also potentially do some nice damage to Mega Gardevoir after surviving a single Psyshock.
232 SpA Gardevoir-Mega Psyshock vs. 248 HP / 244+ Def Venusaur-Mega: 194-230 (53.4 - 63.3%) -- guaranteed 2HKO
0 SpA Venusaur-Mega Sludge Bomb vs. 16 HP / 0 SpD Gardevoir-Mega: 180-212 (64 - 75.4%) -- guaranteed 2HKO
For Ferrothorn, it can also wall out a lesser portion of the team, not including Tapu Bulu locked into Superpower, Mega Gardevoir, or Clefable. It can however survive Mega Gardevoir's Psyshock+Focus Blast as it's brought in:
232 SpA Gardevoir-Mega Psyshock vs. 252 HP / 4 Def Ferrothorn: 61-72 (17.3 - 20.4%) -- possible 7HKO after Leftovers recovery
232 SpA Gardevoir-Mega Focus Blast vs. 252 HP / 252+ SpD Ferrothorn: 202-238 (57.3 - 67.6%) -- guaranteed 2HKO after Leftovers recovery
It also additionally sets up Spikes to make wearing everything down easier, especially Mega Gardevoir and Klefki.
For Tapu Bulu, it can serve as an effective revenge killer against the huge threat of Mega Gardevoir, being able to switch in on an expected Focus Blast coming at Ferrothorn, and being able to KO with Wood Hammer(Horn Leech also has a 50% chance to KO from full):
252 Atk Tapu Bulu Wood Hammer vs. 16 HP / 8 Def Gardevoir-Mega in Grassy Terrain: 414-487 (147.3 - 173.3%) -- guaranteed OHKO
Behind Reflect it needs a small amount of chip damage: 252 Atk Tapu Bulu Wood Hammer vs. 16 HP / 8 Def Gardevoir-Mega in Grassy Terrain through Reflect: 207-243 (73.6 - 86.4%) -- guaranteed 2HKO after Grassy Terrain recovery
Nothing else can really switch into a Wood Hammer barring Klefki. Sucks that I couldn't submit a Rock core, but I'd need like 4 mons to effectively beat Fairy :/
