In PvE (Player vs Enemy) Events, the player is matched against pre-constructed enemy decks. Because these decks generally remain the same each time the node is played, they can be known in advance. Events pages on this wiki include the deck composition of PvE events.
PvE events are contrasted with PvP events, in which the player battles against decks built by other players for the same event.
In PvE games, as in PvP games, an AI (artificial intelligence) bot controls the enemy's play.
