Yes, you can.You can special summon Synchro Monsters from the Graveyard, but they need to be properly Synchro Summoned first...Just like a Fusion monster. You see, if you properly synchro Summoned a monster and your opponent used "Lightning Vortex", you can simply use a "Monster Reborn" or any other card to recover it; since it was properly summoned. Although, if it is sent directly from your Extra Deck to the Graveyard by a card effect, you can say "bye-bye" to that card for the rest of the duel.
You can use cards like Call of the Haunted (CotH) and Monster Reborn to Special Summon a Fusion Monster from your Graveyard as long as:
Obviously into the graveyard.
Destroyed monsters go to the graveyard, including destroyed Fusion or Synchro monsters.
There isn't a graveyard in Moshi Monsters as the monsters do not die, they just become unhappy.
Destroyed or tributed Fusion Monsters go to the graveyard. They will return to the Extra Deck if something tries to return them to hand or deck.
No.You can put monsters in the graveyard only when your monsters are defeated.
No, Dimensional Fissure only affects monsters that are sent to the graveyard while it is active - it waits for anything to try to send a monster to the graveyard, and banishes it 'instead', it does nothing to monsters already in the graveyard.
Yes because Gemini monsters are treated as normal monsters while on the field or in the graveyard
Just like regular monsters, Fusion monsters will go to the Graveyard if they are destoyed. If a Fusion monster is supposed to "return to the owner's hand" or "return to the owner's deck" because of a card effect, it is returned to the Extra/ Fusion Deck.
i suggest the yu gi oh 5D 2009 starter pack it got 3 normal x saber and 1 syncro rare(yes syncro rare)
You cannot simply decide to do that, for no reason. Cards will go to the graveyard or removed from play zone when directed to by an effect, or when you use them as a cost, depending on the wording of the cards.
no, because the monsters are already in the graveyard use a card like monster reincarnation or monster reborn to get the cards back on the field or in your hand then fuse them together.
Use a Dimensional Fissure Deck or something similar it removes from play all cards that go into the graveyard so.. there wont be nuthin in the graveyard for Sky Scourges to feed on =D
