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.
There isn't a graveyard in Moshi Monsters as the monsters do not die, they just become unhappy.
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
"no.... there's a reason it says "from your hand or field" right in the card text. :)" Fusion Gate has no specification on it like that...
Obviously into the graveyard.
Yes.
Destroyed monsters go to the graveyard, including destroyed Fusion or Synchro monsters.
If there are three Gusto monsters with the same exact name in your Graveyard, you can use Symbol of Heritage. You cannot simply use Symbol if there are three monsters in your Graveyard that share "Gusto" in their card name.
Yes as long as you have 4 lightsworn monsters in your graveyard with different names. Remember that Judgment Dragon's summon does not require you to remove the monsters from the graveyard (unlike Chaos Sorcerer), so if the condition was correct for one Judgment Dragon, it's still correct for another.
Monster reborn and Call of the haunted
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.
