Eldlich deck running the Dogmatika engine to hate on the extra deck. A bunch of Rotas let you put El Shaddoll Apkallone into the GY to find the new trap, thus setting up Winda and maybe an extra negate. Forbidden Droplet gives us a spell speed 4 way to help shut down a board full of negates in the high end, and also the benefit of pitching Eldlich cards is pretty high. Eldlich numbers are pretty standard, Extravagance and Magicians' Souls work together to gather card advantage, and no longer requires bricks since Dogmatika monsters are spellcasters.
The extra deck includes a few different packages. There isn't a lot of room for hand traps in the deck, so I'm running packages of 6. Nibiru and Dark Ruler are for combo matchups, though you can also run a combo of Dark Ruler and Forbidden Droplet for Spell Speed 4 negation. Effect Veiler can come in as a generic hand trap, which is generally useful in stopping the opponent's turn, usually alongside Imperm. Lightning Storm, Red Reboot, and Anti-Magic Arrows are for backrow matchups, Eldlich, Altergeist, Guru, to stop their traps, though some Eldlich decks must be treated as combo decks instead. I'd like Cosmic and D.D. Crow for the mirror, but hating on the extra deck and making Winda should help against combo variants, and hopefully the high consistency helps pull ahead against more pure control variants.
