I agree with Goblin Welder which makes a devastating combo with Wurmcoil Engine . Which is a card you should put in this deck!! Would you say this is 1v1 or group play? I can see both but i am just wondering if it is competitive in multi player ?

Ok last thought on this have you considered Karn, Silver Golem ?? He would be insane plus he can kill your opponents lands to buy you time if needed.

kaleb11 and Jeggard my sideboard are the cards im working on getting and are gonna for sure be in the deck. Right now its going EXTREMELY good ive been wrecking in 1v1 like it blows my mind at how much damage it can do with these burn spells or just sacing artifacts to blow shit up like it really is beyond my expectations and as far as multiplayer it does good i mean i have to stretch out my mana at times and there is some drawback but for the most part it survives unless everyone goes after me which they have at times haha if anyone is curious about the deck i recommend you built it with your our style and tweaks of course its a very fun deck.

I think i will build it and i will be changing a few things due to meta got one last card that i think would do well is Darksteel Forge making all your artifacts indestructible is always fun.

Jeggard i promise you youll have tons of fun with it and Darksteel Forge is already in the deck

Quicksilver Amulet , Mycosynth Lattice , Liquimetal Coating might be good here.
