Okay what you have here is an artifact-based Polymorph deck. That deck uses Polymorph on tokens from, say, Sound The Alarm!, which get sacrificed to bring out a Progenitus or Emrakul, the Aeons Torn . The use of tokens from spells ensures that you'll never hit anything but the fatty you want. Building on a budget, I would recommend, firstly, that you make your deck more controlling. Use cards like Mana Leak and Delay (which is a budget Remand ) to stay alive and protect your combo. The advantage is that you don't have to run tutors like Dimir House Guard and Fabricate , since you can just wait the game out until you draw one. I would go blue white, to make use of token creators like Blade Splicer and Master's Call for your artifact tokens. Alternatively, you could go black-blue for Gild and Puppet Conjurer . White is probably better, though, since you can always just try to win with your Blade Splicer and it gives you access to Rule of Law , Stony Silence and Day of Judgment out of the sideboard (if you plan on making one). Next up, I really like See Beyond . If that's in your deck, it means that when you draw your Blightsteel Colossus , it's not an auto-loss, and it lets you pitch cards for better ones. If you can come up with a few bucks, Serum Visions and Sleight of Hand are very strong, but if you're comfortable with two mana Telling Time works quite well. Lastly, I would recommend a smoother mana base. Try to work in some dual lands somewhere. The cheapest decent ones are probably the Refuges from Zendikar, like Jwar Isle Refuge . There's also Azorius Chancery and co., and if you want to work up that food chain you can go to things like Glacial Fortress , Temple of Deceit , Darkslick Shores and Adarkar Wastes . Some utility lands like Halimar Depths and Dread Statuary could go a long way, too, but make sure your colors are adequate and enough untapped lands for your deck to be speedy. Oh - and trim down to 60 cards. The consistency is worth it. +1 for the creative idea!

Sorry, I meant Raise the Alarm .

Thanks ProfessorDucky! I will get rid of tutors add delaying stuff like Mana Leak and add white!

Odd idea for a deck (probably a different deck, but along the same lines.

Has anyone ever tried using 4x Inkmoth Nexus and 4x Blinkmoth Nexus for this?

Using those... and maybe 4x Master's Call ... with no other creatures, you could have Blightsteel Colossus come out with either Polymorph or Shape Anew .

This would give you 8 cards to get your combo off and 8-12 things that can be used to sac. - The nice thing is that it's in U/W for a nice control combo deck.

Thopter Foundry may fit as well... 2 mana to cast, and only one to create the token (can sac itself). Probably only useful if you have a few other artifacts (mana ramp?) in the deck.

I like the Master's Call option.... T3, "draw-go" leaving 3 mana open... end of turn Master's Call .... Followed by T4 Polymorph or Shape Anew

NOW THAT!!! Rayenous, would be a deck I could get behind... I know I wouldn't want to be in front of it :)HostOfSmallPox do that.I'll play you with my Melira, Sylvok Outcast deck

This is what I (very) quickly threw together... I'm sure there's lots of tweaking to be done to it still.

I like Inkmoth Nexus and Blinkmoth Nexus , but I don't like the rest of the deck. It is two weak in the early game
