I run 5 different decks:
Gravekeepers - Used them for the past year, and love them, nothing shocks an opponent more, when their scapegoats and Spirit reapers are gone fast, with added damage to boot
Clown Control - Using the Dream Clowns, usual Spell Stall cards, and a pair of Horus LV6, its nice to be passive most of the time, then a final Horus attack. Also has a nice load of the Flip Summon effect monsters to cause havoc.
The Chaos Cookie Cutter - This is actually a deck I build for my brother, its the bog standard one, but it uses 2 Ohka's for added fun.
Macro Cosmo - Recently proxied, and then recently finished, uses Soul Absorbtion for buttloads of extra LP, plus the use of Spirits like Dark Dust and Yamata Dragon, those D.D's work well with them
Elemental Hero - Always wanted to build one, and now I have, its geared more towards being competitive than Jadan-like. The only downside is that it is a proxy deck, since I have only 1 shiny E-hero fusion so far, and thats Steam Healer, so its a fun deck for now.
