TM on Tyranitar

B/C Tyrannitar is the best Mewtwo counter.

Powered up Mons are mainly needed for raid battles these days. As legendaries will very likely be released by the end of next week in Chicago and soon thereafter everywhere else I definitely wouldn't roll away the best Mewtwo killer moveset...

I wouldn't change it unless you have literally no rock attackers.

Not unless you're willing to roll Fireblast. Personally, I wouldn't touch it.

No, Absolutely No.

No, just no.

Yep, agree with all of the above on TM. Don't do it. Fire blast would suck, and then you'd use another TM on it to get back to Crunch (50%). Keep raiding T-tars, and when you get one with Fire Blast, then use the TM.

I disagree mildly about B/C T-tar being the best Mewtwo counter. Scizor with Fury Cutter and X-Scissors is devastating, doing strong damage and resisting psychic. T-tar is tankier, but Scizor will do damage faster, and in a raid, DPS is the name of the game, not taking damage. Crunch has pretty low DPS for a big attack, and T-tar is in real trouble if Mewtwo has Focus Blast (being double weak to fight and not double strong). Bottom line, to take out Mewtwo efficiently (as part of a team, it will be impossible to solo), you probably need both, start with Scizor and end with T-tar.

B/C is awesome. In fact, I have a B/SE Ttar and I was debating changing it to B/C, but I was too worried about rolling Fire Blast.

Fantastic psychic counter and really great neutral attacker -- B/C is awesome stuff.

Evolve some Geodudes and rhydons and Omastars if you're really desperate for rock attacks.
