Wildfire Revisited - advice?

[Ninja_Bob]

I don't even remember the original Urza's Block Wildfire deck list, but I've always liked it.  And with Voltaic Key being unrestricted, I thought I'd make a deck of it again and make use of Type I rules.

2 Creatures
-----
2 Darksteel Colossus (originally phyrexian colossus)

15 Control
-----
4 Wildfire
4 Fire / Ice (originally Arc Lightning)
3 Mana Drain (originally Mana Sink)
2 Urza's Rage
2 Confiscate

11 Misc.
-----
1 Phyrexian Processor
1 Tinker
3 Temporal Aperture
2 Copy Artifact
4 Thoughtcast

28 Mana
-----
1 Mana Crypt
1 Mox Diamond
1 Chrome Mox
1 Sol Ring
1 Mana Vault
1 Grim Monolith
4 Gilded Lotus
1 Tolarian Academy
4 Volcanic Island
4 Seat of the Synod
4 Great Furnace
4 Darksteel Citadel
1 Strip Mine

-Tinker + Colossus is an obvious win condition.  Can also get lucky with a Aperture to get him out.  Phyrexian Processor was in the original build.  Sometimes it's just better against some decks.  If all that fails, go for the burn and finish with a Urza's Rage.

-It's only 56 cards so far.  I don't have access to Power 9.  And I only own 3 Mana Drains.
-Too much mana?
-Anything else you think I should add?
