I had to take care of some family issues and was late coming back, so I missed the tourney. I built these three decks in advance for it.
Rock Hard Dilgo (40 card pulvy/SS stall)
I expected that pulverizer would be useful because I was expecting shields, particularly gravity shield and dimensional shield. Gravity shields could've taken care of most creatures, wardens could've taken care of anything momentumed, and stoneskins would help protect against catapults an.
Mindgated! (grav/aether duo, gate for gravity opps will surely use, TU for OD dilgo, electrocutor for momentum/dilgo/wardens)
Like Asinickle mentioned, Lobotomizer appeared to be an excellent choice, and TU overdriven creatures can be quite good; the opponent never knows for sure when you're going to pull it out. The mindgates were a little silly, but knowing that everyone would have to be using gravity guaranteed that they would've been quite useful, and I figured there would probably be a lot of aether as well.
Dilgo's miraculous sanctuary
Quite similar in many respects to the first deck, only with more healing and less control. I see that ZsoZso used something very similar, with slightly different numbers of copies of some cards, but mostly the same.
