Fatal Arena

Players enter a proving ground to build army of various beings, equip them with weapons and abilities and cast a diverse array of spells - all to survive in the arena as long as possible. Fatal Arena is a quick battle game, where the fate of all players depend on a single deck of cards. Players look for ways how to build effective offense AND defense from the small number of cards they can gather each game. Plays similar to Hearthstone or Magic: the Gathering, with simpler rules and a unique yet straight-forward resource system: your "resource" is simply the number of cards in your hand. —description from the designer
