It just came up in another discussion that there's something of a bootstrapping problem going on with new topics here on Cake. I basically just want to put it out there that this game exists, and I'm willing to talk about it if there are other fans.
This post would be a bit weird if it ended here - so, although I'm not an expert and without further ado, some information about this game: it is a free-to-play (actually the most generous game in that regard that I know of) card game similar to Magic the Gathering. You and your opponent build decks consisting of unit, spell and weapon cards, and then try to reduce each others health from an initial 25 hit points down to zero to win the game. Each card comes with a cost and optionally some "influence requirements" that the player needs to spend to cast it. In order to do that, players can play one power card each turn.
To give you an idea about existing cards and game mechanics, here's a random pack I opened recently. It contained the "legendary" (very rare) spell Light the Fuse, which puts five cards in the opponent's deck, each of which deals five damage to the opponent when they draw the card. It's not really a good card, because a player might not draw the damage spells at all, but it's real fun when it happens while the opponent only has less then five health left.
To get a discussion going: If you're interested, ask me anything about this game and I will try to answer it.
