Regionals are coming up soon and I am having sooooooo much trouble deciding what I should play.

I have access to pretty much any deck I wanna build excpet DaD and Lightsworn.

I don't own Fossil Dyna's but can borrow 3 if Anthony lets me.

The decks I have in mind are:

Gladiator Beasts (So heavily prepared for nowadays)
Anti-Meta Volcanics
Big City
Any Type of Monarch build (Corn, Turbo, Disk W/ Limit, Oppression, PC if Anthony were to allow me to borrow his D-Draws)
BushiBox

I've been testing my Volcanic deck and it's working pretty good but I'm having problems with preparing my win-conditions (if that makes sense).

So, guys, what do you think I should play?

i got beat by VM

Yeah I know.

I'm leaning somewhat towards GB still.

Volcanic. It's not worth it playing GBs at anything beyond locals anymore because EVERY single MAIN DECK not to even mention the side has answers to them now. Triple Bottomless, Oppressions for not Special Summoning decks. You'll get raped, G. Don't do it. Go volcanics you can even maybe main some Royal Oppressions yourself. Prime Material + Oppression/Vanity's Fiend = GG

I did really well with GB today at the All Ways Gaming City Championship.
Even though people are prepared for it it's really good.

oh how'd you do?

6th place....

I went 4-1 but I lost 1st round to a guy who ended up 3-2 =/

Oh Shoot
