I used my Masterball on Mewtwo.
I tried to use that it had an M on it and kinda had a color pattern to match Mewtwo. Also that it kept breaking out of my Duskballs, Timerballs, and Ultraballs. It kept using barrier and Recover which fucked up my False Swipe set up and would eventually just Struggle itself to death over and over.
Then my friend suggested I use a quickball.
I guess the only reason Im upset now is because I didnt think of this
