Crater's Claws and Devil's Play has spots waiting for them. Maybe Comet Storm would work.

Also, why Solemn Simulacrum?

cool idea,check out my angry birds deck

Goodness gracious!

DERPLINGSUPREME Think you'd appreciate this.

Hey, Demonfire! Hey, Blaze! Hey, Disintegrate! Hey, Steel Hellkite! Hey, Flameblast Dragon! Hey, Mons's Goblin Raiders!

hehehhe... balls.

Bonfire of the Damned :P

Elspeth, Sun's Champion would be pretty nice

Impact tremors or purphous might be better then outpost seige, making secure the waste a fatal win con form casting.

Vexing Shusher in the SB because pumping 13 mana into tokens then getting it countered would suck

Do you use Outpost Siege to dig? I wonder about the include of this as I don't see any immediate benefit from it. Impact Tremors was mentioned, and I think that has more synergy with the rest of the deck. Otherwise, I might up the count of Martial Coup to the full playset, then add in the one-of Banefire for use against Control. +1 from me though, this is a really nice deck. I've never seen Tron lands used to this effect.

With so much card draw and mana from the 1-drop artifacts, I don't think that having so many of the Urza lands is necessary. Two of each one would do. That would give you room for three Snapcaster Mage and a land combination of Steam Vents, Hallowed Fountain, and Mana Confluence. Surprise blockers and timely flashback effects could give you the edge you need. You will need Arid Mesa anyway in order to fetch the 'Vents. The 'Confluence can be subbed by another 'Vents or another 'Fountain if you so desire.
