Deku and dabi are debatable but stain for sure is not the best on this list

Deku mastery is by far the worst out of all of them having a trash passive and ungodly cooldowns. Dabi mastery isn't fully finished given he still needs a passive and spawn animation. Stain mastery has incredible combo potential, a great passive, and has the best implemented mechanics, so stain by far.

CAN'T VOTE...I haven't gotten mastered yet due to groundedness

can't you just play sneakily? you got a phone, and you can just beat up noobs if mobile is too sh*t to play, i sneakily go on my devices all the time, my dad doesn't suspect a sh*t.

Chat I pressed Dabi by mistake, don’t jump me
