In the rule Tricks, change the description of L’Aria to read as follows:

The sum of the Hefts of the cards your Pocket is higher than the sum of the Hefts in your opponent’s Pocket; can only be claimed when the Pockets of all players in the current game contain at least two cards. Points: 1

Add a subrule to the rule The Game, called The Magistrelli System:

High-level Giolitti still uses the Magistrelli ranking system to determine the relative skills of players.

Each Player has a Magistrelli score, which is an integer that defaults to 10. Every time a Player gains a peg they gain 1 Magistrelli, unless their opponent had a higher Magistrelli than them at the start of the game, in which case they gain half of the difference between their own Magistrelli and that of their opponent at the start of the game, rounded up.

For each Player, once add their current number of pegs to their Magistrelli score.
