Battle Dex is a new free-to-play turn-based strategy/collectible card game the developers at Bandera Games say is similar to "Advance Wars + Magic: The Gathering on a hex grid." The game has just entered closed beta testing, and they are planning an online tournament this weekend with a $500.00 cash prize, kicking off a tournament schedule with over $5,000.00 in prizes. This forum post has more details on the beta testing.
