This deck is built to summon powerful sychro monsters as fast as possible. Some of the main combos include:
-Red Sprinter+Red Resonator -> Red Rising Dragon+Red Resonator -> Red Dragon Archfiend
-Masked Chameleon+Archfiend Cavalry -> Red Dragon Archfiend
-Vice Dragon+Dark/Flare Resonator -> Red Dragon Archfiend
After summoning Red Dragon Archfiend, your best method of summoning your end goal, Red Nova Dragon, is through the use of Chain Resonator. You can use Resonator Call to make this combo more reliable, and at this point, your Red Nova Dragon should be adequately boosted up with Tuner monsters in the Graveyard from the previous summons. While this is your main goal, the deck contains many other sychros that you can use as stepping stones to the bigger monsters if you need to so you avoid having an open field or risk your combos getting completely shut down.
This deck's main weakness is card effects that can shut down your powerful monsters. This is partially mitigated by Monster Reborn/Call of the Haunted, but if it becomes a problem, adding some protective cards may not be a bad idea.
This deck is a deck that I've been using casually against friends, so it does have some banned cards in it. The side deck has replacement cards if you're using it in a more formal setting. Overall, this probably isn't the most meta deck, but I'm not familiar with all the new summon types at this point because I just recently started playing again, so it's a style that I'm comfortable with. It is not built around the Link ruleset so that is something to keep in mind. Happy dueling, and let me know what you think!
