finally the recognition it deserves! next you might look at my boi Doomengine! I ask you to consider its PvP value too. ever since the poison immunity its actually been surprisingly good on the occasions ive used it in pvp. (though those are limited as is my pvp. i just think it has a bad reputation as a meh performer when actually its kind of similar to mons like Tardigrenade which are really good in the right setup but often avoided for clunkiness).
One other point id like to bring up. i think you might be overvaluing the Karma Chain guy in PvE. he is very good but i dont think he is top tier. im actually surprised that you rate a monster with conditionally restrictive moves so highly when usually you are pretty critical of them.
