PvP
In PvP (Player vs Player) Events, the player is matched against decks built by other players for the same event. This game mode is not "true" PvP, since an AI (artificial intelligence) bot controls the enemy's play. The AI is inferior to a skilled player in both its gem matching and its card strategy.
Players are divided into Brackets are of a size that matches the Rewards structure. Players may be matched to battle against players from any bracket, but their scoring is recorded in their separate brackets' tier lists.
PvP events are contrasted with PvE events, in which the player battles against pre-constructed enemy decks.
PvP events are often unpredictable due to the unknown nature of the opponent's deck.
