Final team member

Hello.

Two things I need. First, I need a sixth teammate to complete my team. The team I created centers on stall, but I think I need a sweeper that harmonizes with the rest of the team yet poses an offensive threat to other teams. Second, I need someone to look at the team overall and see if it works well together, especially the move-sets.

Note: This team is for WiFi battling, not Smogon battling, so please keep that in mind when making recommendations.

if you are planning on making stall the team does not require offensive presence. even though you wish to have a sweeper i wish to recommend something like weavile it is the closest you should get to offensive presence on stall weavile allows you trap problem mons with pursuit and revenge kill mons with ice shard and icicle crash. i recommend a choice band set with those three moves + knock off.
