I played many decks with similar builds in 2007-2008. Check out this thread:
http://www.themanadrain.com/index.php?topic=35901.0 It will be very educational.
This is the last version of the deck I played:
Creatures
4 Greater Gargadon
4 Magus of the Moon
4 Simian Spirit Guide
4 Vexing Shusher
2 Viashino Heretic
Enchantments
1 Blood Moon
Artifacts
1 Black Lotus
4 Chalice of the Void
1 Lotus Petal
1 Mana Crypt
1 Mox Emerald
1 Mox Jet
1 Mox Pearl
1 Mox Ruby
1 Mox Sapphire
2 Pithing Needle
1 Sol Ring
4 Sphere of Resistance
2 Sword of Fire and Ice
4 Thorn of Amethyst
1 Trinisphere
Lands
3 Ancient Tomb
11 Mountain
1 Tolarian Academy
Sideboard (15 cards)
4 Dead/Gone
2 Pyroblast
3 Red Elemental Blast
2 Martyr of Ashes
4 Relic of Progenitus
It couldn't compete now, but I had a lot of success back then. Magus of the Moon, Greater Gargadon, and Vexing Shusher all had excellent synergy. I'd build a deck around that core and go from there.
