- The effect of "Fusion Recovery" targets a total of two cards: one "Polymerization" and one Fusion Material Monster.
- When Fusion Summoning with "Polymerization", you can use a monster which is face-down on the field as a Fusion Material monster. When doing so, you must show it to your opponent to confirm that it is a proper Fusion Material.
Mentions in Other Rulings
- The effects of "Thunder King Rai-Oh", "Black Horn of Heaven", "Solemn Judgment", and similar cards cannot negate a Special Summon by another card effect.
- King of the Swamp: If you have no copy of "Polymerization" in your Deck, you cannot activate the effect of "King of the Swamp", and you cannot activate "Fusion Sage".
- Macro Cosmos: You can still activate cards like "Polymerization" or "Power Bond" and Fusion Summon while the effect of "Macro Cosmos" is active and removing from play the Fusion Material Monsters instead of having them sent to the Graveyard. If "Polymerization" is activated while "Macro Cosmos" is active, then the Fusion Material Monsters to be sent to the Graveyard will be removed from play instead, and the Fusion Monster will still be Fusion Summoned from the Extra Deck.
