BC

A Special of this type may be played during a Battle in which the first of your opponent's Characters is knocked out of the game, thus preventing him from bringing in the Reserve at the beginning of the next Battle. For example, if a player were to knock his or her opponent's Character out during the first Battle, he could play the Special and his or her opponent's Reserve Character would have to sit out the second Battle. This Special cannot be played to force an opponent's character back in to Reserve. If this Special is drawn after the opponent's Reserve Character has already entered the Battle, it does not need to be discarded as unusable.

Meta Rules
Meta #59 Specials which affect a Character's ability to come up from reserve cannot be played to force the Character into reserve.

Meta #95 Specials which affect how things occur in the next battle prior to the Battle phase (e.g., before placing begins in the next battle) can be negated in the battle in which they are played. Once the next battle begins (and the effect has already taken place) the Special is no longer in play (it is discarded to the Dead Pile) and cannot be negated. Specials which last longer than the placing phase can still be negated.

Non-Meta Rule Information
This Special can only be played in the battle preceding the battle in which the reserve would come up to the front line.
