A fun synchro deck based around summong multyple versions and evolutions of Red Dragon Archfiend.
The deck is semi-competitive and you might brick some times (for me it happens in 1 out of 10 duels so it's not terrible).
You would ussualy go first and hope your opponent doesn't have a way to stop your plays. A great opening hand is Crimson Resonator + level 4 non-Tuner monster. Special Summon Crimson, then summon non-Tuner, go into Red Rising, revive Crimson and then use Crimson's effect to summon more tuner and go into other plays.
The deck has some decent field destruction, effect negation and A LOT of beatsticks. I put Red Supernova because it's just a very fun combination of beatstick and negation, but you can put whatever you want,e though you can can summon it on first turn to flex on opponent ;)
Most of spells and traps are there due to my personal prefrences and you can change them, but you should keep at least 2 Resonator Calls, 2 Resonator Commands and 2 Iron-scrap Signals.
