Like the PX person said, Absol is pretty badly outclassed by other sweepers like mega Gyarados. Hawlucha only works when it can reliably activate unburden. Because you have no Tapu Koko or electric seed, you can't reliably activate unburden and you should replace Hawlucha with Keldeo. Give Mimikyu a life orb for more power. Replace its drain punch with shadow sneak to hit faster opponents. Give Garchomp a dragonium Z to break more walls. Replace its iron head, dragon claw, and crunch with stealth rock to lay hazards, swords dance to raise physical attack, and outrage for a stronger attack. Give Rotom a leftovers and 252 HP/252 SpA/4 SpD modest for more bulk. Replace its thunderbolt and hex with volt switch to reduce the need to predict switches and defog to remove hazards. Give Kartana a choice scarf and 252 Atk/4 SpD/252 Spe jolly for more speed. Replace its night slash and psycho cut with knock off for (usually) more power and sacred sword to cover steel.
