The idea of this deck is to control your opponent's mana.

Let me preface the description with the fact that I'm looking for ways to consistently make it through the early game. I have a really hard time dealing with agro decks as it takes me a while to establish land control.

The main combo is having all of the Tron pieces up. Urza's Tower, Urza's Power Plant, and Urza's Mine combo with Mishra's Helix to deny your opponent mana.

By tapping Mishra's Helix on your opponents upkeep, you force them to only play instants.

Fog and Pacification Array try to get you through the early game by preventing damage and tapping down their attackers.

There is also quite a bit of land removal/denial. Acidic Slime, Mold Shambler, and Terastodon all have that ability to destroy at least one land. Plow Under is also really good at delaying draws.

Late game control pretty much follows the format: Tap down there lands, and use Helvault to exile their creatures.

Any cards suggestions or strategy suggestions are greatly appreciated, thanks.
