Here's the plan: This deck is to play in multiplayer. The goal is to be invicible and furthermore immortale!
First, Try to get all of the tree urz land to give you 7 colorless mana. To get them easily, use Expedition Map.
For the first combo get some Bottled Cloister and Ensnaring Bridge you be immediatly intouchable. In fact, because you don't your hand, other players can't attack you and you draw a card at the beginning of your next upkeep! You can use alsoNorn's Annex so the other playes will have to pay mana white or 2 hp to attack you. Its advantage is that it work also for the plainswalker's abilities!
After you can use Mindslaver with Academy Ruins, with 11 and U mana, you can control someone during every of his turn and indefinitly!
Sure, there'S direct damage to kill the party... But I found a great solution called Well of Lost Dreams. You can gain life with Trading Post by discarting or with Sun Droplet or Wurmcoil Engine. If you can, try to have as much Sun Droplet as you can in play so you will always recover your life and if you pay mana you can draw cards insanely. To get your life faster, useElixir of Immortality. You will gain 5 life and you will shuffle your graveyard with your library so you cannot mill yourself. Instead, it gives you the opportunity to control the game even more!
The game is going to fast or you are in a bad position? Use All Is Dust to clean up the board and keeping your things. Also, use Trading Post to be able to get back some important cards from the graveyard or gain life or put a 0/1 goat to defend you or draw cards! If the game is really not going well or you want to get more control, use Storage Matrix so no one will be free to do everything they want.
I added some tutors as Fabricate and Reshape and Eye of Ugin to get your things faster. I use Chromatic Star to draw a card without losing my mana and instead I can convert to colorless mana into blue or white mana.
To get the full control of the game, I put Ugin and Karn to be sure that no player could escape to your control!
