Can Fusion Recovery add back monsters sent to the Graveyard by Future Fusion before the Fusion is Summoned?!
Future Fusion has sent materials to the Graveyard, and you want to use Fusion Recovery.
Yes. Those monsters are still treated as Fusion Materials for that Fusion Summon.
Can Fusion Recovery return a monster that was banished for Miracle Fusion and later returned by Burial from a Different Dimension?!
Fusion Materials were banished by Miracle Fusion and later returned to the GY by Burial from a Different Dimension.
No. Once a monster is returned from banishment, it is no longer treated as a Fusion Material used for a Fusion Summon, so Fusion Recovery cannot return it.
