The list of top-DPS counters to Mewtwo includes Ash-Grenina and Pheromosa, which are nowhere near release, as well as Mega Absol/Banette/Houndoom (are all in the game yet?)
A way to filter out unreleased species would make the DPS-TDO spreadsheet FAR more useful.
It would be helpful, as would options to show longer lists, say, 25 and 50 on one screen, plus a “show species best moveset only”.
For reasons we went into on the recent “the appraisals aren’t up-to-date” thread, I can’t see it happening.
The Mega-Helldog and Mega-Flock of Seagulls dog have been released but given the disinterest in Megas until the recent change to their system it’s entirely forgiveable not to know that. Even now, mega-evolving something each day is right at the bottom of my task list.
