Honchkrow and Froslass for Spiritomb
Gardevoir and Scizor can handle Roserade
Roserade for Gastrodon and Milotic, use Stun Spore to help with slowing down Milotic and its Ice Beam, 1 Giga Drain should be enough to take down Gastrodon though.
Gardevoir can handle both Lucario and Garchomp, Froslass for Garchomp too - I took hers down with a Togetic, its not hard.
