using master hand is stalling
No it's not >.>, unless you have a weird definition of stalling.
takes forever to choose your character
Not if you know how to do it well.
have to delete a ton of names on every setup
No you don't
every game goes to 8 minutes and freezes afterward.
Only if he loses, so it's not the Masterhand player's fault. It doesn't take that long to reset a gamecube after the match anyway.
Add onto that the fact that it's highly unlikely a set with a masterhand player will go to game 3, it's not
that bad in terms of how long the set would take.
HBox vs Armada would take longer
the fact that I can contest port priority, get 3rd port, and then you can no longer use your character makes it such an obviously sketchy "character" choice.
Ports are decided before characters, so someone doesn't have to go Masterhand if you choose 3rd port, and at least for counter-picks, they're assured 3rd port.
this is a case of don't be an idiot.
Eh, unless he's explicitly banned in the ruleset, technically he's legal.
He's a terrible character anyway (in singles, he's broken in doubles though), and goes 100:0 with other characters when the opponent knows what they're doing.
In any case, to the guy who's asking, the TO is highly likely to not let your friend pick Masterhand, even if he's not banned in the ruleset, which is a little silly, but meh, he should be banned anyway.
