Nearest-era rulings (Tengu, Sept 2011) — no REDU-specific archive exists.
Card effect (current official text)Once per turn, you can select 1 of your opponent's monsters that is removed from play. Until the End Phase, this card's name is treated as the selected monster's name, and this card has the same Attribute, Level, ATK, and DEF as the selected monster. If this card is removed from the field while this effect is applied, remove it from play.
Rulings
- "Scanner" targets 1 removed from play monster, but does not continue to target after the effect resolves. If "Scanner" is removed from the field while it is not copying another monster (example: if it is destroyed during your opponent’s turn), it is not removed from play.
- If "Skill Drain" is activated after the effect of "Scanner" resolves, the effect of "Scanner" is still applied, and "Scanner" will still be removed from play if it leaves the field.
- If the target of "Scanner" is no longer in the removed zone when the effect of "Scanner" resolves, then "Scanner" does not copy that monster, and "Scanner" will not be removed from play if it leaves the field.
