Time Vent (タイムベント) is a keyword introduced in CB10, exclusive to Kamen Rider Odin. The keyword's text reads:
- Time Vent - (When Attacks) By banishing 11 "Kamen" family cards from your Trash, the opponent sends their own cores to the Void until they have a total of four cores on their Grandwalker Nexuses/Field/Reserve/Trash. Neither player's effects can prevent this effect.
In-universe, Time Vent is Odin's ultimate card, which allows him to rewind time, represented in-game as returning the opponent's core to the amount a player start the game with, technically returning the player to their first turn.
