Help me to improve my Evil World Deck (Evil Hero Gaia+Dark World)

I need to improve (if possible) this deck. I don't run Gates to Dark World because i need to keep DW on grave (for Dark Calling). This deck is designed to be as quick as possible.

1x Beiige
3x Broww
2x Goldd
3x Grapha
3x Snoww
2x Gem-Armadillo
2x Gem-Knight Alexandrite
1x Gem-Knight Crystal
1x Gaia Plate
2x Effect Veiler

2x Dark Fusion
2x Dark Calling
3x Upstart Goblin
3x Dark World Dealings
2x Dark World Lightning
1x Extra Gate
1x Monster Reborn
1x Heavy Storm
1x Dark Hole
1x Foolish Burial

1x Fiendish Chain
1x Trap Dustshoot
1x Solemn Judgment

Extra:

3x Evil Hero Gaia
3x Steelswarm Roach
3x Utopia
1x Utopia Ray

I use Koa'ki Meirus as the Rock fodder in my build. 3 Guardian, 3 Wall, and 2 Sandman to make it a more control-oriented build.

Terrible, DW has no synergy being removed, the point is to stay in grave for gate fodder and constantly bounced for Grapha
