Notes & Combos
Ideally you synchro climb through rciela and diabell into auxila, add standup, make whatever interaction you can (baronne, apollousa, little knight, azaminas) before using the field spell to set trudea, dance for primera, add wake-up and use it to summon crimson dragon.
It's fine to use auxila as summon material because most of the time you want to use wake-up from GY to send phalanx and summon her back.
Unfortunately azamina plays are the only way to make omninegates before the 5th summon that aren't awkward but the deck is very resilient to handtraps that aren't called droll or dimension shifter. There's a lot of room for interesting lines and adaptation.
Didn't get to test any new centur-ion cards. Some thoughts on my picks:
Goat Ogre - Beats Millennium Engine, beats True Light, beats Sangen Summoning, beats a lot of backrow non-sense going on this format.
Talent - Handtrap heavy format, if you draw it there's a good chance it will resolve, if it doesn't you can always chuck it away at multiple points of your combo.
Queen Azamina - Fun card, definitely not needed but I believe she pulls her weight. Keep in mind the only way to trigger her GY effect to summon herself is fusing her off Sinful Spoils of White Forest or Hallowed Azamina.
Phalanx - Consider running an extra copy of this. If you hard draw into either Centur-Ion Wake-Up or Stand Up it means you're going to search for a Centur-Ion card you don't need, with 2 copies of Phalanx you would actually get to use it for disruption.
Blazar - I'd probably benefit from a sifr instead of two blazar, I just think two blazar is funny and makes it nearly impossible for your opponent to outgrind you in case they don't scoop.
Synchro Rumble - Personally prefer not to include, but it's not a bad card, easy to send for effect activations and can setup an extra body to use with field spell or Woes.
Floodgates - In theory deck should be able to run anti-spell and a few others to really seal the deal against striker tenpai etc. I just didn't want to use them.
