Help me fix my Dark Deck?

Question

This deck is ok, but I continuously lose with it. Help me fix it so that it will win some duels. I prefer to have only 40 cards and all monsters must be dark.

Monsters: 21

2X Armageddon Knight

2X Dark Armed Dragon

2X Dark Crusader

3X Dark Grepher

1X Dark Nephthys

1X Doomsday Horror

1X Night Assailant

2X Obsidian Dragon

1X Rainbow Dark Dragon

1X Sangan

1X Spirit Reaper

1X The Dark Creator

2X Vampire's Cruse

1x Reshef the Dark Being

Magic: 11

2X Allure of Darkness

1X Final Ritual of the Ancients

1X Heavy Storm

1X Lightning Vortex

1X Mystical Space Typhoon

1X Premature Burial

2X Reinforcement of the Army

1X Smashing Ground

1X Beginning of the End

Traps: 8

1X Bottomless Trap Hole

3X Escape from the Dark Dimension

2X Judgement of Anubis

1X Mirror Force

1X Torrential Tribute

This deck must be tournament legal which means the forbidden and limited cards lists apply. Thanks!
