Can you create Variant tournaments?

(question above)

They exist lol go to variants and then arena tab

So how to create one?

Only CGAs and Admins can create tournaments.

Please tell us what tournament would you like to do. Having a plan, in order to promote it and try to get a participation as massive as possible would be the best proposition to obtain our support to your tournament. You can message me, for instance, to discuss your idea. Take care.
