Been absent from the thread for a while, and I apologize for not lurking a bit more, but I was wondering if anyone had managed to make TTar a sufficient check/counter to MegaCharY. I've been struggling to deal with MegaY and I'm trying to adjust my TTar to fulfill that role. Here are some sets and calcs I've been looking at.
AggroWPTar
Tyranitar@ Weakness Policy
Adamant
252 HP / 252 Atk
1. Stealth Rock
2. Stone Edge
3. Crunch
4. Filler
Calcs
So scenario one, both TTar and CharY lead, CharY almost certainly switches out anticipating Stone Edge and TTar can get SR set up.
Scenario two, Charizard switches into something else on your team before mega evolving, and you try to switch TTar in to counter him.
So this set can wreck CharY as long as it gets a hit in. Problem is, as CharY will always outspeed TTar, taking 75-90 from solar beam on the switch means CharY kills TTar with Flamethrower/Fireblast on the next hit before TTar ever even gets to hit back. Just straight up fucked it seems.
Special Tank TTar
Tyranitar @ Weakness Policy / Leftovers / ?
Careful (+SpDef - SpAt)
252 HP / 252 SpDef
1. Stealth Rock
2. Stone Edge / Rock Slide
3. Crunch
4. Filler
Calcs
252 SpA Mega Charizard Y Flamethrower vs. 252 HP / 252 SpD Tyranitar in Sun: 102-120 (25.2 - 29.7%) -- guaranteed 4HKO
So scenario one is exactly the same as the above set as always.
Scenario two, TTar takes up to 65% on the switch in, and then up to 30 from flamethrower on the second hit, JUST BARELY surviving to hit back with SE or Crunch or something, the latter of which has the possibility of 0KOing after Weakness Policy but isn't promised, so the EVs would have to be toyed with there if you wanted to ensure the higher accuracy without sacrificing Stone Edge for Rock Slide.
+2 0 Atk Tyranitar Crunch vs. 4 HP / 0 Def Mega Charizard Y: 271-321 (90.9 - 107.7%) -- 50% chance to OHKO
Running assault vest on this bulkier set, thereby sacrificing the possibility of SR, seems helpful at first, because...
252 SpA Mega Charizard Y Solar Beam vs. 252 HP / 252+ SpD Assault Vest Tyranitar: 146-174 (36.1 - 43%) -- guaranteed 3HKO
But even granted that, switching into that, and seeing that he only took 43% from Solar Beam, it's unlikely that CharY will even stay in to give TTar the chance to hit back, instead leaving him facing some other counter with half his health gone, and unable to take another hit from CharY like that.
So any other suggested sets for this problem?
