REDU format ruling
Monster Recovery

Nearest-era rulings (Tengu, Sept 2011) — no REDU-specific archive exists.
Card effect (current official text)Target 1 monster you control that is owned by you; if that monster is still on the field, shuffle it and your entire hand into the Deck, also, after that, draw cards equal to the number of cards you shuffled from your hand into the Deck by this effect. (You cannot activate this card if you have a card in your hand that is owned by your opponent.)
Rulings
- If you select a Fusion Monster or Synchro Monster, it returns to its owner's Extra Deck.
- If you select your opponent's monster that you currently control, it is returned to your opponent's Deck.
- You can select a Monster Token. It is removed from the field instead, because it cannot be shuffled into the Deck.
