Not sure if this belongs in this thread but has anyone tried a prison build with success? This is my current build.

Mana (28)
4 Ancient Tomb
4 Buried Ruin
4 City of Traitors
4 Ghost Quarter
4 Mishra's Factory
4 Wasteland
4 Mox Diamond

Panzer (12)
2 Batterskull
2 Karn, Silver Golem
4 Lodestone Golem
4 Metalworker

Locks (14)
4 Chalice of the Void
4 Smokestack
4 Tangle Wire
2 Trinisphere

Others (6)
4 Crucible of Worlds
2 Sundial of the Infinite

I really like this deck, though still needs some fine tuning.
Smokestack goes really well with Tangle Wire and Sundial of the Infinite. If I have all three pieces on board, it is pretty much game.

Crucible of Worlds plays a huge role because I can mana lock my opponent, have a sacrifice vessel for Smokestack, or recur my lock pieces with Buried Ruin.

I decided to go with Batterskull because he is StP proof. If he does get countered or destroyed, I have Buried Ruin to fetch him back. Lifelink is always good with Ancient Tombs in my deck.

Karn is simply awesome to turn all my locks into beaters. If my opponent kills my germ token, I can turn Batterskull into a beater and before bouncing him back.

I really like this list right now. Still Tinkering with numbers and adding other cards. Though, maybe this belongs in MUD Stax, if such threads exists.
