Thats not a flaw at all Skibur, flying weapon decks arent even overpowered or that good. What is overpowered is rainbow decks, I suggest Zanzarino should encourage mono-decks more by making you get 2 quanta per turn from your mark if you have a mono deck.
This game doesn't have the API, therefore it can't have badges. Alexofxen, all elements in this game are perfectly balanced (except rainbow) and darkness, fire and entropy are definately not OP.
