GRIM the Card Game

From BoardGameGeek:

GRIM is a two-player tarot-inspired Expandable Card Game creature battler designed by Grimoire Games. Venture beyond the boundaries of life to a world where The Fiend reigns, imposing his will upon the Grim who war over the Spirits who roam there. For an eternity, the Fiend has cast his shadow upon the Grim, forcing them to battle for his entertainment. But you, a powerful and strategic Grimlord, are positioned to stand against him with your Grim to finally end the strife. In GRIM, players combine two Elemental Grim Decks each embodying a unique style of play, to face off in an undying war. The strategy of GRIM begins with players' decisions regarding how to pair these Grim Decks together, as each Grim Card has Synergy Effects that will only trigger when played next to certain Elemental Grim. Attach Spirits for powerful Spirit Bonuses, react with Elements to negate and manipulate Attacks, and position wisely as you and your opponent place terrain effect Afterworlds in play. Secure enough knockouts and you will win the war. -description from the designer
