Erebe is a 1v1 PvP competitive Online Card Game available for free on PC. The focus is on simultaneity, with players having to make important decisions at the same time, and interactivity, giving competitors the means to react to their opponent' actions.
Each phase of a turn is played simultaneously with the opponent. Anticipate his decisions to plan your strategy and thwart his offensives! At the beginning of each round, you draw until you have 5 cards in your hand which gives you a wide range of options. Finally you also need a good management of your mana, which is conserved between each turn, if you want to play epic and devastating cards.
