Enact a new rule entitled “Checks and Balances Treaty” as follows:

Any Signatory to this Treaty has their Reach defined as not the sum of the Breadths of all Treaties to which that Emperor is a Signatory, but instead, twice the sum of the Breadths of all Treaties to which that Emperor is a Signatory.

An Emperor may not become Signatory to this Treaty if they are Signatory to more than three other Treaties. If any Signatory to this Treaty (besides the Player) is ever a Signatory to more than three other Treaties, they cease to be Signatory to this Treaty.
