So I'm making a team to destroy a friend that doesn't know about EVs, IVs and just uses level 100 legendaries and pseudos like Garchomp without ever setting up. He hasn't played since Gen4 and only singles.

So far I got skarmory with spikes and whirlwind, orthworm with slow shed tail, contrary malamar with baton pass, superpower and stored power, and the 6th slot is an air ballon kingambit (if he ever gets that far). But I don't know what I should use as the sweepers to pass the baton pass buffs. I was thinking a physical sweeper as the 4th slot, maybe Tyranitar or Annihilape? And a special sweeper as the 5th slot, but I don't know who, I need one that can eat earthquakes and/or dragon physical moves.

Any ideas?

Don't worry about making him cry, he's 30.
