I was thinking about it, but I get totally pooned by the Brainstorm restriction and missing Timewalk. Mostly the Brainstorm restriction.
Of course, I could also just scrap the idea altogether and go with a Legacy build with red over black and no expensive cards besides the duals. But then I lose the really cool stuff.
I was planning on just putting my old Trinity Keeper together, since it's pretty terrible:
Blue (20)
4 Force of Will
4 Mana Drain
1 Misdirection
1 Ancestral Recall
1 Stroke of Genius
1 Braingeyser
1 Fact or Fiction
1 Mystical Tutor
1 Power Artifact
2 Morphling
1 Time Walk
2 Brainstorm
Black (6)
1 Vampiric Tutor
1 Demonic Tutor
1 Chainer's Edict
1 The Abyss
1 Mind Twist
1 Yawgmoth’s Will
Green (2)
1 Regrowth
1 Sylvan Library
White (3)
1 Balance
1 Dismantling Blow
1 Swords To Plowshares
Artifacts
1 Zuran Orb
Mana (28)
2 City of Brass
1 Undiscovered Paradise
4 Underground Sea
3 Tropical Island
2 Tundra
1 Tolarian Academy
4 Flooded Strand
1 Library of Alexandria
1 Dustbowl
1 Wasteland
1 Strip Mine
1 Grim Monolith
1 Sol Ring
1 Mox Sapphire
1 Mox Emerald
1 Mox Pearl
1 Mox Jet
1 Black Lotus
Sideboard:
4 Oath of Druids
2 Krosan Reclamation
4 Duress
2 Call Of The Herd
1 Aura Fracture
1 Scrying Glass
1 Ensnaring Bridge
But without the Timewalk and some other tweaks like Future Sight over a Morphling, improving the mana base and sticking some Impulses in there. Oh, and then I get to run Hystrodon in the board for the aggro-control component, which is totally awesome. But I also may not be sideboarding, so that could be irrelevent.
I suppose the draw to pre-Exalted Angel Keeper lists is that they're primarily reactive; whomever my opponent might be, they get to play their cards and I have to find the answers. Of course, the Trinity build was designed to be much more proactive, so it might not be the best direction to go in. But putting Power Artifact on Grim Monolith is still pretty awesome. So is Fastbond/Zuran Orb/Crucible of Worlds, but that requires a post-Onslaught card (albeit one with decent artwork).
I dunno, I'm at a loss.
But those ToC lists are awesome. It's like Type 1 to the extent of "Land, Lotus, Mox, Mox ---> First-turn Craw Wurm" compared to what's being developed today. I think that should probably be my goal here: doing not really broken stuff with broken cards. The TurboSpaz list looks really tempting. Hmm...maybe something with Haunting Echoes...could be too sadistic though.
