It doesn't matter what your mark is, nor what quanta the deck produces, Deck Classification is based solely on what from elements the cards that make your deck are from.
If I have 24 Quantum Towers and 6 Elite Skeletons, it's a Mono - Death deck, and a quite ineffective one. If I have 18 Quantum Towers, 6 Elite Skeletons and 6 Cremations, it's a Duo - Fire/Death deck. It's pretty simple
This would be a

deck.
