evs: 252 HP / 4 Def / 252 SpD
-EV spread lets it 2HKO max HP / max Def LO Rankurusu but there might be a better spread idk all I do is speed creep
-mention Ice Beam for Gliscor / Landlos
-mention Thunder Wave
-mention Chople Berry / Balloon
Interesting set, and if it's effective for a specific time, that's good. I feel, however, that this Tyranitar's trying to do so many things at the same time, with the moves and the EV investment and all. I think the set should go along like zis:
name: Specially Defensive
move 1: Pursuit / Dragon Tail
move 2: Crunch
move 3: Ice Beam / Fire Blast
move 4: Dragon Tail / Stealth Rock
item: Leftovers
nature: Sassy
evs: 252 HP / 252 SpD / 4 Def
ivs: 0 Speed (To take Nattorei Gyro Ball better)
Basically, Pursuit or Dragon Tail; your choice. If you really want to screw up momentum and damage the switch-in, Dragon Tail. it also takes advantage of entry hazards and Tyranitar's own Stealth Rocks. Pursuit is there to counter Ghosts and Psychics (especially Lati@s), obviously.
Ice Beam, assuming Gliscor doesn't invest in Special Defense, will do 94% minimum to it, and it will KO once Gliscor has taken Stealth Rocks or prior damage. Lure it with Crunch, then hit with Ice Beam.
And yeah, Dragon tail + Stealth Rocks is good, but you don't have to go with that combination if you already have Stealth Rock support.
EDIT: Also, the Stealth Rocks comment goes for MixTar as well. Don't run it if you already have a guy for that. As for Fire Blast, it doesn't quite KO specially defensive Skarmory or Nattorei, but it's nice. Not sure about Super power because it's technically weak.
