>>48257278I only played Battle Spot so these were for that
Singles:
Switcheroo Klefki holding Iron Ball caused many salty jap tears on Battle Spot. Mega Banette with Phantom Force, Sucker Punch, and Destiny Bond too since most people didn't realize PF hit through Protect and at worst it turned every single 3v2 into a 1v1. Protean Assault Vest Kecleon was fun too with Rock Slide, Drain Punch, Shadow Sneak, and Sucker/Fire Punch.
Doubles:
Choice Band Electrode with Explode
Motor Drive Electivire with Ion Deluge
Turn 1 Ion Deluge had priority and turned Electrode into a suicide bomber with a banded 250 BP STAB move that boosted Electivire's speed by 1 tier while breaking sashes or outright killing what wasn't immune/resistant. I'd usually throw out a Charizard Y afterwards for the EQ/Heat Wave spam but occasionally went with Cryogonal to snipe Garchomps or a ground/Volt Absorb-er for Discharge spam
Triples:
Magic Coat and Stealth Rock Kecleon
Something with Wide Guard
Mat Block Greninja holding Air Balloon
Adamant Justified Mega Lucario
Timid Beat Up Charizard with 1 speed higher than base Lucario
Turn 1 Kec used pebbles or Magic Coat, Lucario used Agility, and zard used Beat Up on Lucario to give it +6 atk
Turn 2 Lucario went mega and used Earthquake/Rock Slide, Charizard switch to Greninja otherwise Heat Wave or Air Slash, and Kec died.
Turn 3 Wide Guard user comes out and uses it, Gren uses Mat Block, Lucario uses EQ.
Turn 4+ is cleanup
There's holes in each strategy, but they were fun and produced high quality rage quits
