the deck seems good, but wouldnt a 3rd "solar recharge" speeds it more? and "allure of darkness" will do as well, altough u dont wanna remove ur monsters.
i think that "doppel warrior" will do great in the deck. its a Dark monster and a target for junk synchron". its like "junk synchron's" own "dandylion" :3
also if i run mst i run 2 or none, idk why :S
and what about "gorz"? i mean if u mill its food for chaos sorcerer and if ur opponents cleans ur field (brd or something) u still got a defensive/offensive card back at ur sleeves.
"burial of a different dimension" could help as will "return from the different dimension", but only if ur certain u got enough removal cards...
these just were some suggestions and i hope it helps
i totally forgot O.O "Pot Of Avarice"... i know u need ur monsters in ur grave, but what if u milled "JD" and "Chaos" ? its a great topdeck when almost milled ur whole deck..
i think i have said enough xD
