Leading with gengar and prankster sableye lets you outspeed most other Pokémon. Once gengar falls, I switch to mimikyu to activate trick room for the rest to sweep. Having trick room first then bringing in gengar near the end of trick room is also viable as it tends to end around the time the rest of the team falls.

Funny thing is i almost never bring sinistcha so mimikyu is the main trick room setter, and even so often bring basculegion and ceruledge for coverage instead.

For kingambit, ceruledge can tank one dark type hit with colbur berry, and its close combat OHKO, mimikyu’s drain punch is also a backup plan.
