Forum:Zebulyon's Assault deck

I have for a long time tried to build an assault mode deck, but I have run into a problem I dont know how I will improve it. So I have decided to create this page in hope that someone might give me some advice.

Assault Mode deck v.1
Monster 3x Assault Beast 3x Goblindbergh 3x Bri Synchron 3x Top Runner 2x Assault Mercenary 1x Stardust Phantom 3x Dark Tinker 2x Stardust Dragon/Assault Mode 1x Colossal Fighter/Assault Mode

Trap 3x Assault Mode Activate 1x Starlight Road 1x Scrap-Iron Scarecrow 1x Solemn Judgment 1x Ultimate Offering 1x Mirror Force 2x Seven Tools of the Bandit 2x Bottomless Trap Hole

Spell 1x Lightning Vortex 1x Heavy Storm 1x Stardust Shimmer 1x Monster Reborn 1x Pot of Avarice 2x Assault Teleport

Extra deck 2x Stardust Dragon 2x Colossal Fighter 1x Red Dragon Archfiend 1x Brionac, Dragon of the Ice Barrier 1x Red Nova Dragon 2x Gaia Knight, the Force of Earth 3x Number 39: Utopia 1x Steelswarm Roach

I have for the moment a problem regarding if I scould put in another Assault Mercenary or put in a Mystical Space Typhoon. I have tried to make so that the deck use the effect of Goblindbergh to summon an assault mode monster on almost the first turn. What I feel it´s lacking on i that pretty often end up with my assault monster on hand but i feel like it would be stupid to put in another Assault Teleport because it might very likely turn into a dead draw please state your opinion on this.
