Help needed for my 3:3 team for Singles: Maison/Battle Spot

[Almonds]

1. Sharpedo
Speed Boost + Attack Raising/Spe Attck Lowering Nature
Evs in: Max'd Attack and Speed. Rest in HP
Item:?
Protect
Poison Jab
Waterfall
Crunch

I gave it Poison Jab just in case it has to go up against Fairies/Grass-types


2. Volcarona
Flame Body + Spe Attck Raising/Attck Lowering Nature
Evs in: Max'd Spe Attack and Speed. Rest in HP
Item: Sitrus Berry
Quiver Dance
Fiery Dance
Bug Buzz
Hurricane


All I need is a third member. I am losing way too much in the Maison - I can't unlock Super Singles :/ Also, Singles is the hardest rule in the Battle Spot for me.

I was thinking about an Electric-type (Mega Ampharos?), but if there are other better options, I'd like to hear about them.

FWG core works, maybe a defensive grass type like M-Venasaur to give some bulk and power to your team. I'd suggest a bold for defense. This set works well,

Venasaur@Venasaurite
Overgrow=> Thick Fat
Bold
252 HP/4 Def/252 SpD

Gigs Drain
Toxic/ Sleep Powder
Sludge Bomb
Leech Seed

EDIT: just thought about the omnipresent Talonflame. I'd suggest replacing Volcarona with a special fire type or Arcanine with Wild Charge. You can put a focus sash or leftovers on your sharpedo.

Entrainment Truant Durant + Set-up sweeper with Protect wrecks the AI in the Maison.
I'd recommend Dugtrio, as it's very fast and has a move that boosts 2 stats. The only downside to Dugtrio is that it's very frail, and wrecked by priority.
Volcarona also works as a setup sweeper, just replace Hurricane with Protect.

Staraptor with reckless HA ability and a choice band / life orb pretty much destroys normal singles mansion. Just spam brave bird until all dead .

For the 3rd member, maybe try:
Kangaskhan (Kangaskhanite)
252 HP/252 Atk/6 Speed
Power-up Punch
Return
Earthquake
Sucker Punch

It can get boosting thanks to Parental Bond and Power-up Punch, Return for STAB and Earthquake for coverage while Sucker Punch lets you hit faster 'mons or those packing priority.

I'd recommend a Focus Sash on either of the other two Pokes, just as a warranty against anything unexpected.
