Here's the deck I've been using. All you need to do is summon Phantom Skyblaster or Cosmic Compass, generate a token and tribute both for Tyrant's Tirade. After that, you can safely summon the Wall. Use Dark Mimic Lv3 (Lv1 won't work) as a drawing engine and to summon Dark Necrofear. During the last turn, use shield and sword and go for the Vassal Union combo.
I'm running a variant of this, but with a slightly different end game:
Phantom Skyblaster x3
Stray Lambs x3
Tyrant's Tirade x3
Cat of Ill Omen x2
Curse of Royal
Temple of the Kings
Celestial Transformation
Mystical Beast of Serket
BEUD
Shield and Sword
Gravekeeper's Vassal
Secret Pass to the Treasures
Union Attack x2
The point is to have 6 cards capable of generating the double token for Tirade.
