I have been playing since half January, I really love the gameplay (yeah I love magic). I just really like the fact that I can play online magic whenever I want without having to resort to 90's graphics (I tried that and I ran away from the horrible experience of magic online), since I live in the middle of nowhere and there's no one to play with here. I spend like 60 dollar to get wildcards, which to me makes the game quite enjoyable. I made 1 tier-1 deck (RDW) and a few semi-jank decks (with God Pharao's Gift, I love reanimator stuffs, and a midrange GB).
I would think that if you want to go full-on f2p, it will be pretty nasty if they don't improve the economy. Which is something they should really do, else the playerbase will probably dwindle sooner than later, which is bad for all of us who want this game to succeed. So fingers crossed for the next economy update, but I don't have very high hopes seeing what they did to try improve stuff in the past few months (like removing wildcards from the vault, then putting them back, etc).
Anyway as far as I know there will just be 1 more final wipe when the beta goes public (and no one knows when that will happen). Until then I'll just keep doodling around a bit.
