Alpha Sapphire Battle Masion team

I'm tryin to make a team resembling my awesome SoulSilver team. I can't trade and I have no way of transfering my team.

Dusclops @ Quick Claw

Impish
- Shadow Sneak

- Will-O-Wisp
- Pain Split
- Confuse Ray
His role was to open, burn the opposition and out last it, using Pain Split to heal. I can't evolve a Dusknoir.

Weavile @ Scope Lens

- Faint Attack
- Low Kick

The revenge killing machine. I'm not even sure what to replace him with. So much win.

For my last spot I'm thinking Mega Gardevoir sweeper. Still have to do more research and get all the breeding items.
How can I best replace my team with others to fill the same roles? This team will be used for all the Battle Masion modes.

What does your SoulSilver team consist of? If we could gather info on it, it'd likely be more easy to lend suggestions.

Anyhow, one thing I would recommend trying, first and foremost, is to perhaps remove Quick Claw from Dusclops, and give Eviolite. Dusknoir's very tank-y, and its pre-evolution could be even more do, in a way, if it was given this particular item to hold. I've tried Eviolite Dusclops a couple of times before; it was decent, I would say!

As for your third team member, Mega-Gardevoir does sound like a good option. Alongside, another Pokémon we could consider carrying is Togekiss. With para-flinch strategy, it has chance to wreak some major havoc.

The two that i posted are part of my team with the third being a Togekiss. Thats one I'm planing on replacing with Mega Gardevoir though. The moves I taught it are quite amatureish and its nature isn't great.

Yeah not the best attacks, but I really tried to go with my gut and pick useful moves. The main problem I have is replacing my revenge killer Weavile. As I said before, I don't knoe where to start with that. Seriously gave Evolite a thought and I think I'm gonna try get it in my SSilver game. As awesome as I think my team is, I only have one banner thingy and thats at the Arcade. I hope the extra info helps.
