I picked up the Summoner Wars: Master Set a few months ago, right around the beginning of the year. The game is absolutely great and I have been playing it as much as possible since then. Not sure if any of you other folks have tried it out, but I figured I would give my recommendation here.
Summoner Wars is listed as an "expandable card game of tactical combat." That description works fairly well. It's sort of a cross between Magic and chess with hand/resource management thrown in. Also, it is #2 in Tom Vasel's top 100 games.
I play on Vassal and there is an ios app with some of the factions. So if anyone plays or is interested in the game let me know.
