Meta Rules
Meta #53 Specials with lasting effects remain in play even if the Character who played the Special is K.O.'d.

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.

Meta #134 If one Special sets up a condition and then a second Special comes along with text that directly contradicts the first Special, then the Special played later takes precedence. On the other hand, Events always override the text of Specials.
