The main thing the deck does is use Mathematician or Armageddon Knight to dump monsters for their effects while using the one-time Zephyros to gain a +1 as well as recycle the monster used to send it to the graveyard. Triple Bora and a single Gale help to provide support for Zephyros, either making a rank 4 play or opening Black Rose as an option. Felis can be sent with either Mathematician or Lavalval Chain and can be spun back to the deck with Edge Imp Scissor - note that Dante won't trigger Felis or Shaddoll Dragon, but they're still worth playing because of Mathematician, and Dante is still a brilliant card.

Dark Armed Dragon and Black Luster Soldier help to provide bulkier monsters that can clear the way for direct attacks and big swings. The triple Sanctum and double Moralltach also allow for a little bit more control during your opponent's turn. Note that Moralltach and Gale also provide a way into level 8 Synchros, and Gale can halve an opposing monster before you do so.

I've only played singles with this but found it really consistent - even if you seem to brick, the two copies of Soul Charge make playing out of awkward hands a bit easier.
