perhaps tyranitar should be banned, simply because sand stream would completely destroy regular teams since leftovers is banned.
And leave no counters for sunny day/ rain dance teams?
Seriously, without tyranitar to remove the sunny day for eggy, i think eggy would sweep the whole team. Just sunny day, solar beam, solar bear, psychic, repeat.

Wish would be a champion since there are no other recover moves other then rest/ morning sun and gang.
Perish trappers would own too, without good moves to bring them down in time.
Flail/reversal are quite common with heracross.
What about a bellyzard or bellylax? belly drumming lax using body slam and chesto rest would totally destroy this tourney. Same goes for a bellyzard.
Cosmic power, when used with stall teams, especially without the common moves, would be an unkillable. Taunt/ingrain/mean look are still there to deal with roarers and the like.
