Slay the Titan : Deckbuild RPG

This is an intense, competitive online card battler with a roguelike deckbuilding core, playable in short, interruptible sessions. While it offers high replay value and can be played one-handed, progression is heavily skewed towards pay-to-win mechanics and an energy system limits playtime. It's best suited for players who enjoy strategic card combat and don't mind the aggressive monetization.
