>>53046953>>53049639A theoretical if Tyranitar could learn Rock Slide (legal), Power Gem (legal), or Meteor Beam (illegal).
The legal Rock Slide change is 15.189 DPS (37.58 ER).
That's still out-performed by Rhyperior with 15.931 DPS (39.51 ER) and Tyrantrum with 16.018 DPS (37.4 ER).
Mega Tyranitar would have 18.132 DPS (47.84 ER), out-performing Mega Aerodactyl with 17.864 DPS (42.49 ER), but losing to the unreleased Mega Diancie which may have 20.42 DPS (46.2 ER).
The illegal Meteor Beam change is a wash, gaining a 20.171 DPS (53.22 ER) thanks to bulk to substantiate a 977.6 TDO.
This is without specifying an opponent mind you. For Mega Blaziken raids, Mega Aerodactyl may be a better choice for being neutral against fighting damage, instead of doubly weak.
