Notes & Combos
This deck is seriously underrated.
Regenesis Dogmatika is a control deck with the added niche of using "2500 atk and/or def" handtraps and board breakers. It also (almost) doesn't care at all about many floodgates and, as such, we can use them.
If you can survive turn 2, you probably win through endlessly cycling through your monsters over and over again.
Maxx C / Fuwa aren't much of an issue because you don't need to special summon everything right away thanks to Regenesis Birth, and Bystial control can get rid of SO much of the non-meta decks by itself like Tear and Raidraptor (surprisingly popular) and has some usage against Maliss and Ryzeal. Just set and/or summon whatever you have in hand whenever it's best and you're good. Playing around Droll is also possible by using Code during the Draw Phase search Archfiend or searching Lord via Regenesis or Archfiend during the Main Phase > set Birth.
Going 2nd you can drop the Golem in their heads multiple times, by sending it back to YOUR hand via Warrior or Nadir>Malong, and other backroll/control decks won't be able to outgrind you as long as you can make sure your monsters don't die during your turn without Birth.
Had a blast, most fun I had in YGO since Tear 0. Everything feels impactful.
