First, you should not call anyone a god. Theres only one. Only one f2p deck wins against p2p so far. I suggest a team mode with chat. Weekly events to get new cards isnt a bad idea (but not so grindy like wwe scard). A weekly leaderboard with rewards is a must. Maybe separate f2p and p2p completely when you get more users (like runescape). If you are offering just 3 f2p decks then ppl will be forced to buy into p2p area. Good game all and all. If you like Magic the gathering download this asap.
