Regulators are a balloon class shared by Red and Blue, thematically they are inflatable game referees with red ones style after modern sports refs while blue ones are styled more after Gyoji. normally they serve as a way to ref pickup games but have often found themselves in the fray of the match themselves.

Mechanics wise, Regulators act as Rule pieces, typically they cannot attack or block but apply global passives that effect the game pace for all players.

Red regulators generally provide effects that expedite the game pace, like giving all balloons speedy, replacing the Defender effect on balloons with Sentry (They can attack rival balloons but not players), or speeding up resource access.

Blue regulators on the other hand, try to slow down the game by establishing limits on what balloons can attack, reducing the number of cards restored at the start of your turn, or applying penalties for actions in the form of discard or having balloons stunned.
