Are the jokers playable?

Are Mega Man, Pac Man, Kuro, Toro, and Cole viable for competitive play? I’ve tried checking their forums, but there is no info.

they are banned from tournament play so define “competitive”

Competitive as in ranked matches.

They’re all playable, although you’ll need gems to buff up their health (800 for Pac-Man and Megaman, Cole and Toro 750, 600 for Kuro). Cole is pretty cool IMO, his zoning game is quite good.
