Notes & Combos
Not running Auroradon cause halqdon was my least favorite MD format and I had enough of it for a lifetime. Anyways general goal is to try and get seals plus a rank 7. Dracossack can make tokens for Cherubini to dump Water Enchantress so that's the preferred one, but if you already drew Rite or had to normal and use Thunder L3 effect to get started you can make Voloferniges instead. Cherubini and Dracossack can be linked off into Dispatchrazzi to prompt a summon for Fateful Adventure, it sounds kind of stupid but I didn't see any productive turn 1 Link 3s and Dispatch helps dissuade people from forcing the Seals bounce with an early battle phase. If you have an extra monster you can make 3 mat Appo instead though.
Seals is insanely flexible in this deck, beyond the obvious bounce it can set up for next turn by grabbing Magnamhut, possibly dissuade OTKs with Druisworm or Nowru Aries, set up nasty disruptions with Albaz into Mirrorjade (Albaz triggers the Armed Thunders which is funny), or potentially stun your opponent with Koa'ki Meiru Drago, especially if they enter early Battle Phase to force seals out.
Speaking of Drago it is incredibly good in this deck for this meta, it can be searched with Tempest which is accessible by Thunder L5 and therefore can almost always be found if need be. While it's a bit risky to commit super hard to it going first in a BO1, when a certain insect rears its head it's a hail mary play you can go for that works pretty often in this Tear/Spright/Branded meta. When ordering plays going first I recommend starting with a way to discard Thunder L5 or get out Pile Armed Dragon so that you don't need any more special summons to reach it if Maxx C comes.
