* You cannot use [[face-down]] monsters to perform a '''Synchro Summon'''.
* You can negate a [[Synchro Summon]] with "[[Black Horn of Heaven]]", "[[Horn of Heaven]]", "[[Thunder King Rai-Oh]]", "[[Royal Oppression]]", etc.<ref>[http://yugioh.faq.konami.jp/EokpControl?&lang=en&tid=43674&event=FE0006 Konami FAQ]: [Basic Rules] Can you negate a Synchro Summon with a card effect?</ref>
** In this case, you still send the monsters to the Graveyard. The Synchro Monster is not considered properly Summoned, so you cannot revive it with "[[Monster Reborn"]]". In addition, effects like "[[Odin, Father of the Aesir]]"'s do not activate, since they have not yet reached the field.
* If the Synchro Monster requires [[Synchro Material Monsters]] of a specific [[Attribute]] (like "[[Hydro Genex]]"), you can use a monster with multiple Attributes (like "[[Elemental Mistress Doriado]]") as a [[Synchro Material Monster]].<ref>[http://yugioh.faq.konami.jp/EokpControl?&lang=en&tid=44605&event=FE0006 Konami FAQ]: [Basic Rules] When Synchro Summoning "Hydro Genex", can you use a monster with multiple Attributes as a Synchro Material Monster?</ref>
* The monsters used in '''Synchro Summoning''' are treated as neither [[Tribute]]d nor [[Destroy]]ed.
