Notes & Combos
I didn't want to burn UR dust on this so the extra deck is definitely suboptimal. Centur-Ion Legatia would have been nice I think. I just randomly pulled a second Baronne, but there are probably better 10s you could play instead of the second copy.
Don't run Speedroid stuff without Modoshi Piper. It's incredibly annoying to open just a Terror Top (TTop) without a tuner in this format since you can't link it off. Don't forget that Taketomborg's SS from deck effect locks you to wind. TTop + Piper lets you make Pegasus @Ignister, which is very useful against the Exodia trap that destroys your whole board.
Droll is mandatory for this format. Droll is quite good in this deck going first, since Droll + TTop search TTBorg is also Pegasus @I. It can even make Baronne with any 9, or Omega with Pet Dragon. Ash is bricky for you but good against you so it's worth running one for Crossout. On turn one, it can be used to make a ShenShen or JiuJiu to trigger VW effects in hand. I found Ash quite weak as a hand trap in this format so stay away from more copies.
Harpie's Pet Dragon combos with Droll, TTop, TTBorg, Lulu, and sometimes Nyannyan. It's often worth summoning first to bait a negate.
Be sure to make Ultimaya Tzolkin BEFORE you make ShenShen because it requires you to send to GY. It's the only way to summon Beelze of the Diabolic Dragons, who is a very funny tech card to deal with P.U.N.K.'s boss monster Psychic End Punisher. Notably Beelze is not a UR, which my wallet thanks Konami for.
JiuJiu deals with a lot of irritants like REDDragoon and Unstoppable Exodia Incarnate. Also helps A LOT versus Yubel. Adamancipator Risen - Raptite is a clutch DPE answer in some game states. Yes, I saw those 3 cards a LOT.
