Changeling Titan is a cool card. Never seen it before. Neat deck, synergy seems pretty cool. How does it play?

Smallpox is a cool idea in a deck like this!

I like hating this! Interesting idea, and a cool build.

I've found in colorless artifact decks like this that hangarback Walker seems like fun, but rarely plays as good as it looks.(Even with this decks mana ramp) I'd drop it for another Steel Overseer. (Really I always use a playset of them.) Also have you considered replacing some of the Wastes with Artifact lands?

Admittedly they run from about a dime to2 bucks-but they're worth it in my opinion.

Also this a little pricier than Cloud key, but gets draw so I'd recommend Vanquisher's Banner:

This deck looks like it pumps out the mana base pretty quickly so I suspect even at 70 cards it plays pretty fast. That said I'm always a huge fan of trimming where I can to get down to 60 cards. Seems like removal could be a problem for you-be a real bitch if someone countered/canceled/etc... your mana ramp.

Don't know if that will help, but I'd say overall cool deck and it looks fun.

Interesting deck, love the concept! how does it play?

I always recommend Warren instigator in goblin decks! Free goblins is hard to beat!

Which cuts it down to 65, which is a little more manageable with this particular deck-but I agree that 60 cards has always worked best for my own purposes.

Interesting idea. I like it.

Wow, cool work!

How does it play? Looks brutal!

Great deck, I'd recommend adding Vampire Nocturnus

I picked a [play set up for my wife's Vampire deck. Solid card for a cheap casting cost.

Ouch! It hurts right in the prides! Looks fun!

Llanowar reborn would be a good addition to this:

Maybe not fancy but a good way to return something:

Easy returns!

I assume you made this with cards available, but I'd definitely recommend getting a few more gates Ablaze, and Circuitous Route's. But it looks fun!

I had no idea that Mirror Gallery existed! Awesome card!

I totally recommend Warren instigator:

Free Goblins!

Thanks, I absolutely am interested. Our group tends to have few standard players, sothis is all brand new to me-and interesting! Thanks for the link!

Agreed, he feels out of place. I initially thought about using it to grab Krenko. Now I am less sure.

Nice! I like it.
