I am already overloaded on the 4-drops, but what would you advise they replace? Also, in the interest of keeping this a budget build, I will not be including 'Walker.

i would cut the sidisi's faithful and a thopter spy network for something.

oh! and ghostfire blade. wait this is post rotation nvm

cutting those cards would change the deck too much from the original design. I will consider it, but I doubt it will happen. It's worth playtesting....

What would you cut to include hangarback walker and thought-knot seer ? And how many im trying this but i would like to include them

You could replace the Hedron Crawlers with Hangarback Walker, since they occupy the same slot on the curve, and 'Walker can help delay the opponent long enough to play the 4-drops. As far as Thought-Knot Seer, that one is a bit trickier. I would say that the only card that would be worth replacing would be Captain's Claws. All of the other cards are a bit more important than Claws, so this would be the first card I would attempt to replace.

I like the deck dude it's awesome. I would just like for you to explain the sideboard in the description please.

Foundry of the Consuls sac it and 5 mana for only 2 thopters, you're better off with 2 more Mirrorpool or more other basic lands.

Sorry guys. I'm been away for a while.

@Caran_Lyg - The reason you have Foundry of the Consuls in the deck is for those situations when your opponent manages to wipe your board, and you need Artifacts to start stabilizing. You won't always have a creature for Mirrorpool, so you need another way to get back into the game.

I'm going to try to update this deck, as I've been playing a TON of Modern and Commander lately, and haven't really kept up with the meta. Give me a few, and I'll try to come up with something.

Thanks for all the +1's!
