Здравей :) Няколко коментара:

  • Прегледай имплементацията си на Card отново. Сравнението ти на карти не работи.
  • Защо са ти rank_name и suit_name? Не можеш ли да ги преобразуваш с код?
  • Защо приемаш (&_block), след като използваш yield?
  • Конструкцията [*(cards || create_new_deck(ranks))] не ми допада. Прекалено сложно е и ме кара да мисля :) Това е еквивалентно на cards || create_new_deck(ranks).

Не ми допада, че използваш класовете за тестета като ръка. Ще е по-добре ако създадеш отделни класове за нещата, които връща #deal. Така няма да можеш да напишеш WarDeck.new.allow_face_up?, което е безсмислено за едно тесте. Също, няма да можеш да раздаваш карти от ръката. Това трябва да се прави само от тестето.

Има тук-там и други проблеми. Прегледай пак условието и пробвай нещата. Опитай и с негативни примери - опитай се да счупиш кода, вместо само да проверяваш дали работи :)
