Forum:Help me out with Original Fiend deck. . . please

I'm terribly partial to the Geminis, so I made a Gemini based deck, that evolved into a fiend deck.

Its really very powerful, though not terribly dependable, wondered if anyone knew any cards that would be useful for me.

My general strategy is to get a Doom Shaman on the field with the effect, and use various searchers to put my high powered fiends in the graveyard and then summon them with Doom Shaman. . . Please let me know what I can do to revise.

Monsters: 20
 * Doom Shamanx3
 * Armageddon Knightx2
 * Mystic Tomato
 * Sangan
 * Doomsday Horror (2 more in side deck, they're for saving myself from allure of darkness or stopping Macro decks)
 * Belial - Marquis of Darkness
 * Evil Hero Malicious Edge
 * Dark Valkyriax2
 * Caius the Shadow Monarchx2
 * Blazewing Butterfly
 * Dark Grepher
 * Legendary Fiend
 * Byser Shock
 * Gemini Summoner
 * Evil Hero Infernal Gainer

Magics/Traps: 20
 * Allure of Darknessx2
 * Torrential Tribute
 * Swing of Memoriesx2
 * Lightning Vortexx2
 * Monster Reborn
 * Sakuretsu Armorx2
 * Card Trader
 * Dark Eruption
 * Ultimate Offeringx2
 * Seven Tools of the Bandit
 * Heavy Storm
 * Mystical Space Typhoon
 * Symbols of Duty
 * Destruction Jammer (horribly useful to chain to the death of Doom Shaman to prevent other fiends from being destroyed)
 * Card Destruction

Any help is greatly appreciated. I got trounced at the first tournament I took it to, won 1 out of 3, lost 1 from a bad mistake, lsot another before I had the doomsday horror and i didn't see how badly a macro monarch deck would destroy me, the last was just a damned good elemental hero based deck (or at least I think it was, match was over too fast for me to get a grasp on it). However after the tournament I traded and got the Allures, the Byser shock, dark eruption, and doomsday horror, so its moderately untested in its current state.
