This is an easy reccomendation for those that want an MtG like experience and don't like or can't play the current digital iterations.

Background: I'm an old school MtG player for more than 15 years and the current online renditions of MtG are just not up to par for me as a videogamer for even longer than I've been a Magic player. Arena is pretty close to great, but it is standard only, so, being a old school MtG player, I cannot play with some of my old favorite cards. I left Hearthstone, which I played for 3 years, for this game.

Reasons: 1: Depth. This mechanics are similar to MtG in this game. Defender decides blocks, and you can interact during your opponent's turn with certain cards, unlike some other card games.
2: Economy. Thoughout my short time with the game, I never felt the game was being stingy with resources like other games. I was FtP for my first couple of months and managed to craft a handful of legendaries in that time and make it to diamond. I was impressed that I was able to achieve a rank like that as a F2P player, which is nearly unheard of in other games, that I bought some gems so I could craft more legendaries for fun decks that I wanted to try out, even if they are not competitive.
3: Design: The lore and mechanics really fit well together, and while it is not a super important aspect of a card game, it does help you to stay immersed. The setting is a little bit dark with cyber agumented humans and betrayal, but a little but whimisical with goofy tribes like yeti. A little something for everyone, like MtG.

Conclusion: Basically the ideal digital version of what a MtG game should be if you are not totally commited to the MtG lore. As a long time player of MtG that knew the lore, but not devoted to it, this is nearly a perfect fit, and anyone in the same boat as me would feel the same, I think.
