Ruby battle tower (lvl 100) help

so I'm nearing the final streak of the level 100 battle tower for the second time (got obliterated on battle 50 the first time) and i'm wondering which pokemon i should leave out. The team I've been running with is zapdos (extrasensory, tbolt, drill peck, and baton pass), metagross (rock slide, meteor mash, earthquake, explosion), and salamence (crunch, hydro pump, flamethrow, dragon claw). the pokemon i'm getting ribbons for are farfetch'd and slowking, so I definitely need the two i bring to at least carry farfetch'd.
