You will have a lot of trouble with water types if you are using two pokemon weak to water. I used Tyranitar as set up sweeper before in 4th Gen, and you really want Crunch + Earthquake, because Stone Edge (or even Rock slide) missing will stop your streak sooner than you'd like. Also, Crunch + EQ has better coverage anyway (You could go for Rock slide + EQ for even better coverage, but you don't really want to take your chance at accuracy issues). You do not want Outrage for Tyranitar without Lum and without STAB. Gliscor is not really fast enough to pull off sweeps imo. You're better off with Garchomp and even then it's not as reliable as Gen IV. Uxie can make better use of Bold or Calm nature, but if you only have a timid one then, that's fine, not too huge of a deal I don't think. So yah I'd advise using something over Gliscor that can cover for Tyranitar's weaknesses. You have fighting and kind of Ground covered with Uxie, so try to cover as many of Ttar's other weaknesses with your other pokemon (i.e. cover grass, water, steel, bug...) o yah, Uxie will attract some bug moves, and really, Gliscor won't be able to set up on something like tinted lens Yanmega Bug Buzzes. You might not be able to cover everything, but at least use something resisting bug that at least resists at least some of TTar's other weaknesses and is neutral to the others. Hope that helps.
