I am looking to return in the game. I would like to focus on a deck that is F2p. But i feel that i want a relatively new deck that it will give me time to build and learn. I did that with sylvan and amazones and enjoyed it....
-here some good F2P Deck: lunalight, heavysam, deskbot, red-eyes, photon...
-photon is the best in my opinion u need only to open a mini box twice and u r ready to go. GOOD LUCK.
Try water decks. If you can get your hands on an abyss dweller from the latest box and then a good build from Shark Fang, you are good. Plus you can always use old water favourites as replacement. If you are coming back to the game, you will have a few already.
