Hi this is my first deck submission and I hope I can help out some people with this deck because it is very much fun.
First and for most you want to get to Red Rising Dragon with a resonator tuner ASAP. from there you can go into the "Big Dragons" of the deck like: Scarlight Red Dragon Archfiend, Hot Red Dragon Abyss, Hot Red Dragon Archfiend Bane, Tyrant Red Dragon Archfiend, Red Nova Dragon, Hot Red Dragon Archfiend King Calamity, and of course Red Supernova Dragon.
A little spice I found through testing the deck is "Supay Duskwalker", Not only can it set up your graveyard with a resonator tuner but it can grant you access to a level 6 synchro or a big body for more of a higher level Synchro monster.
honestly I could go on and on how somethings go in the deck but I have a feeling its a lot more fun trying it for yourself.
