I have a Rescue, Sentinel, Nightmare, La Junta and Ulu Watu Deck and I've got 150.000 clintz left. I don't like playing with the Nightmare deck so I wanna replace it with another deck that looks like the decks I have now. Total clintz: Max 200.000 clintz. And which cards of that deck are the best to buy?
You're not giving us a lot to work with. Name some exact cards you own first so we know what you meant by looking like the decks you have now.
You could try playing Uppers, they are a strong clan and viable in most of the game modes.
With that much cash you should have no problem getting some Huracan. They really are extremely enjoyable to play as a clan, and great for elo.
