AER - Tezzeret Control

***BU Tezzeret Control***

Win condition: overrun with big artifacts. Noxious Gearhulk is T5 due to Tezz / Hedron Archive. Herald of Angush, if it becomes mainboard, is T4.

Ramp strategy: lock down the opponent while pushing out additional mana sources (Hedron Archive, Magnifying Glass,

Number of artifacts by cmc:
1) 8 (Pacification Array, Renegade Map)
2) 5 (Metalspinner's Puzzleknot, Servo Schematic)
3) 0
4) 4 (Hedron Archive)
5) 0
6) 8 (Noxious Gearhulk, Walking Ballista)

My primary concerns:
1) I'll be spending mana to lock down the opponent rather than getting creatures out to ramp up
2) Turns 1 and 2 need to be super consistent. But the eight 1cmc artifacts and the five 2cmc artifacts + Walking Ballistae help. I think Turn 3 ends up being my deny-your-shit turn. Drop a 1cmc artifact then hold the 2 remaining to play Fatal Push or Metallic Rebuke
3) I might be heavy on the Noxious Gearhulk and Walking Ballista. Scrap Trawler and Gifted Aetherborn are good substitutes.

If mana isn't coming fast enough:
1) Add Magnifying Glass (3cmc) instead of Hedron Archive (4cmc)

If struggling to control the opponent:
1) Increase Metallic Rebuke or Disallow

What I didn't include and why:
1) Prophetic Prism: drawing a card is great and having another artifact on the field is nice, but it fixes mana, not creates more
2) To the Slaughter: I feel this card needs Delirium to really do I what I want it to do, and I don't plan to be dumping tons of cards to the graveyard

What I might need to drop (some or all):
1) Negate (sideboard): seems like overkill, and while the lower 2cmc is nice, it's only noncreature
2) Pacification Array (not sure how much I'll be using this - depends on how fast my creatures are coming out)
3) Hedron Archive: great for grabbing all the mana I need to add counters to the Walking Ballistae ballista and drawing cards when I'm low, but I do worry about how late it comes into the game
