Night and Light

So I have a Moon Dragon and a Sun Dragon so I figured i'd try to throw something together with them. A lack of Oracle makes this a little hard, but I think I can cope.

Monsters : 20

1x Tragoedia

2x Cyber Dragon
2x Gigastone Omega
2x Ancient Gear Engineer

3x Giant Rat
3x Apocatequil
2x Supay
2x Fire Ant Ascator
1x Medusa Worm
1x Des Lacooda
1x Sangan

Spells : 10

2x Book of Moon
2x Instant Fusion
1x Brain Control
1x Mind Control
1x Mystical Space Typhoon
1x Creature Swap
1x Lightning Vortex
1x Smashing Ground

Traps : 10

2x Dust Tornado
2x Limit Reverse
2x Bottomless Trap Hole
2x Widespread Dud
1x Call of the Haunted
1x Starlight Road

Extra Deck : 15

1x Mist Worm
2x Sun Dragon Inti
1x Stardust Dragon
1x Red Dragon Archfiend
1x Exploder Dragonwing
1x Black Rose Dragon
2x Moon Dragon Quilla
1x Goyo Guardian
1x Brionac, Dragon of the Ice Barrier
1x Ally of Justice Catastor

2x Musician King
1x Darkfire Dragon

So I lose a little bit of search becuase of the lack of Oracle. I think the fact the he can't be Special Summoned when you control a monster really hurts his playability with Rat, and Rat is pretty cool in here, especially with my mini-RatBox. Ancient Gear Engineer makes the cut cause he's Level 5, can easily take out an opposing Oppression/Black Whirlwind/Possible Saber Hole, and he's Rat-able. I wanted a Lily (allows to summon Tempest) or Grand Mole, but Engineer has a bit more synergy with the deck.

Thoughts?
