Yugioh Burn deck. Rate and Fix?

my deck is built this way...and yes it is fun to play...lol. but when i built mine and took it to regionals...i found tht the dimension walls were reli hard to successfully use...so i took them out and added a playset of tremendous fire. my deck also runs the rapid-fire magician dark room of nightmare combo...which makes every spell card deal 700-1000 points of damage plus what the spell card deals. otherwise i like the way you think and good luck to you...we need people like you to help take over the gladiator beast generation!!!!!!!!!!!!!!!!
