Tyranitar's Best Damage Moveset

Stone Edge is slightly better

Tyranitar and Machamp need to watch out for Dazzling Gleam when fighting a Blissey. I almost always use a Rock Smash Rhydon, I don't bother dodging, unless it has hyper beam.

Although SE deals more cycle DPS, Crunch is imo the better move, because it is very energy efficient. This leads to situations where u fire off 6 Crunches vs 2 Stone edges, so Crunch out DPS Stone edge there.

Bite/SE is still his best dps moveset if against neutral targets. Bite/Crunch is not that far behind.

Do note that Bite/Crunch is actually more risky on dodging coz Crunch is a pretty slow move for a 3-bar ( 3.2 secs, even slower than Stone Edge's 2.3 secs ).
