This is definitely the best variant and also my last build. There is nothing more to improve. This deck has no straight combo. You also wanna get into your Crimson Resonator and use Level 4 Monsters to make red rising and bring back Crimson to activate it's effect to special summon up to 2 Resonators from your deck (or hand). If you have the ascator engine plus Crimson Resonator, you can special summon Crimson Resonator and then activate Ascator the Dawnwalker, discard one (Jet Synchron, Destrudo, Dangers, Red Familiar, Stygian Streetpatrol etc) and special summon itself plus Fire Ant Ascator from your deck (or hand) make Chaos Ruler and activate it's effect and then you can use Crimson Resonators second effect.
You can use Synkronresonators second effect multiple times per turn to bounce back resonators and discard them with the dangers to extend furthermore. You can also use Creation Resonator and Synkron Resonator to synchro summon, so you can add back Creation Resonator to special summon it again.
The goal of this deck is to get into Crimson Resonator as fast as possible, summon Chaos Ruler and use Red Rising Dragon multiple times. Also using Synkronresonator multiple times. Then you make boards like one or two Red Supernova Dragon and/or one or more Hot Red Abyss with Void Ogre Dragon.
It really depends on your opening hand, what you drawn into, what you will mill with Chaos Ruler and which resonator you special summon.
