For combo tutorial, check out my previous build. I removed my second Chaos Ruler for a Samsara, because sometimes you need a level 5 Synchro Dark Dragon Monster to combo off and also I am playing currently 3x Resonator Command which pairs well with 11 Resonators, so you always get Crimson Resonator. Also I am playing 2x Red Reign, this card plus a level 8 or higher Dark Dragon Synchro Monster is almost an instant win against most decks.
For the spicy tech I am playing 1x Armageddon Knight, because this card plus Red Resonator is still access to Crimson Resonator. And I am playing 1x Stygian Street Patrol as a target for Armageddon Knight and also Ascator.
