I guess most of us already got a good psystrike Mewtwo candidate (or a few L20/L25) for power up/max out. What have you done on this Mewtwo and for what purpose?
For me, initially I would power up one with good IV for collection purpose if I got a shiny one. However, I don’t have any shiny Mewtwo. I got 3 SB Mewtwo getting dust on the bench and therefore I intend not to get another normal psystrike Mewtwo joining the pack as my gameplay is raids and gyms where Mewtwo is not particular optimal in current meta.
How about you?
