Rate my Volcanic deck.?

first id recommand u lower your monster number by taking out one slicer and one shell.i agree with taking out marshmallon because its not really useful in this deck.u have a lot of copies of most monsters so ull rarely need to stall.i suggest putting another lava golem in its place because something people tend to do alot when confronted with the solar dragon problem is to summon more monsters, which u can sacrifice for lava golem.for your spells, i dont see much to change, it just depends of your strategy.For your traps however,udont have any protection for spells or traps which is why u should consider adding dark bribe.u could ether take out a nightmare wheel or a magic cylinder or whatever else, your choice.
