Може би е добра идея да хвършил грешка, ако подадеш невалидна стойност и този if не се изпълни. Ние няма да тестваме за такива неща, но след като изрично си сложила if, би било добре да довършиш логиката си.

Имайки предвид, че това ползваш само на едно място, вътре в самия клас, а реално ти трябват повече символи да извикаш метода, бух минал и без него. Направо си ползвай len в cut метода.

Ако обхождаш с променлива, която няма да използваш, изполвай _ по конвенция.
Освен това не виждам причина изрично да започваш от 1. Числото е случайно, можеш просто да кажеш for _ in range(cards_to_cut):

Същото и тук. Да, така работи, но ако вземеш предвид посоката в оригиналния Game, ще спестиш дублиране на код. Освен това, ние ще тестваме Game и самостоятелно - той трябва да е способен да взима предвид посоката без да е наследен.
