Floowandereeze but it's super budget

It's first or nothing

With no Dimension Shifter, this deck will absolutely suck going second. Though you will still have some options available to you.

For monster heavy boards, Book of Moon and Forbidden Chalice work great as single monster negates.

Effect Veiler is a nice cheap handtrap that can still be impactful in stopping some plays, such as hitting a Rusty Bardiche to stop them from setting up Fog Blade.

While you can always cut Harpie's Feather Storm cause it is a bit costly, it is still a great turn ender that requires very little set up.

Side deck is mostly just suggestions. Backrow tends to be difficult to deal with so you run the cosmic + duster package. Anti-Spell + Dark Simorgh shuts down spells entirely. D. D. Crow works great against decks such as Eldlich and Sky Striker and is searchable through Robina. Dimension Barrier works great in hindering Swordsoul or Invoked Shaddoll Dogmatika

You can always interchange these cards with board breakers such as Raigeki or Dark Hole. Lightning Storm and Evenly Matched would be great cards here, but they're incredibly expensive.
