I think you mean Darksteel Relic not Darksteel Ingot .

What happens if you draw the Blightsteel Colossus before you can set the deck off? oh, I know, you loose.

fun idea though. but too fragile, you put that dude out and I hit it with a Control Magic , or a Unsummon of a Fiend Hunter or a Lignify or a Silence the Believers or a Act of Treason etc.

I know, I forgot and corrected. And yes you do loose!!! If there are ways to keep him from the top I will be happy. As for the other stuff I will replace Aqueous Form with Robe of Mirrors

One exiler and you are done. No removal, and very little protection. If that one guy gets it, I don't think it is possible for you to win.

There are decks that are do or die, but they are usually turn one or 2 combo decks. This one give many turns to your opponent before you can do anything. I think you would be better off running affinity.

I play tested it a few times also just to make sure I was seeing it the right way. It seems fun, but I doubt it would work.
