Zen - C ++
Ten Codémon nie jest tutaj, aby jeść, ale walczyć. Wie, że martwy wróg nie ukradnie jego jabłek.

Strategia
Wszyscy (oprócz CircleOfLife) pędzą do jabłek, ale nie Zen, nie zawsze. Jeśli wróg może sięgnąć po jedzenie przed nim, po prostu czeka w centrum (co? Ale co tu robisz, CircleOfLife?). W przeciwnym razie Zen podchodzi do jabłka i odwraca się, czekając, aż coś się wydarzy. W rzeczywistości używa jabłka jako przynęty.
Nie zakodowałem niczego przeciwko ciekawej strategii CircleOfLife, ponieważ on może wygrać tylko z bardzo dużym szczęściem.
