Pretty cool blend of Hero Academy (turn-based async fantasy strategy on a chessboard-like map) and MtG, from the makers of PoxNora (if that means anything to you):https://conquestofchampions.com/funding
It's not fully released yet but you can already try it for free, not sure what the limitations are. Seems like it's got a lot of potential, it's certainly much more complex than Hero Academy for better or worse (I suspect balancing might be difficult). There's a single player "campaign" as well as player vs. player (with friends or tournament style).
I believe eventually they will also go to tablets, which may be a better venue for this type of game.
