Duelyst is a digital free-to-play collectible-card-game with a grid. You are a general on that grid, and you summon minions, play spells, and equip artifacts to defeat your opponent; in addition, you can replace one card from your hand each turn. This is a fast-paced card game that looks good, is fun to play, doesn’t abuse F2P too hard, and I willingly bought a purely cosmetic item for it.
