I remember an old 4th Gen team that used Uxie, Vaporeon, Gliscor, Magnezone, Dugtrio, & Weavile to trap & OHKO over half the OU tier with Magnet Pull, Arena Trap, & Pursuit with Uxie, Vaporeon, & Gliscor handling the others.
Uxie was a standard SR lead set with Vaporeon & Gliscor running borderline Trick Room sets to always go last so they could Baton Pass/U-Turn to safely call in Magnezone, CB Dugtrio, & CB Weavile.
With Weather & Ferrothorn flying around, I could easily imagine that team doing pretty well in 5th Gen.
