Right now you can disable special summons.
What I would suggest is to make it so you can set how many special summon one can do for a turn.
From 1 to 25 maybe ? Idk. It seems like a cool idea ! Its mainly for reaching this “anime” style battle.
Doing this restriction with friends without it is possible but you need to keep the summons in head and if you misscount and you dont play in manual you basically cheated and need to FF.
Thats my suggestion for the day ! Have fun coding and playing guys !
