Forum:Question about Synchro Summons

Hello :) I came back to Yu-Gi-Oh after a 2 year break (quit after Crystal Beasts came out) and I'm starting a new deck, as I sold mine on eBay. I discovered Synchro cards, and it made me wonder: Do Synchro cards work the same as fusion monsters in the sense that the material cards can be both in your hand and side of the field, or do they have to be on the field for you to Synchro Summon? Thanks! ♥
