When I first saw this card, I went crazy. There HAS to be a way to abuse it. Indeed, it shuffles only permanents you OWN, not control, in your deck. More importantly, mana pools don't empty.

What do you think of the following? ^^

   Creatures   
4   Dominus of Fealty
2      Illusionary Wall
4      Wall of Air   
2      Pshychic Membrame

   Spells
4   Lich's Mirror
4   Pact Of Negation
1   Fork
1   Twincast
4   Puca's Mischief
2   Red Rituals
4   Volcanic Geyser
2   Fault Line
4   Fabricate
2   Force of Will

   Lands
10   Mountains
10   Islands
   
Creatures  12
Spells          28
Lands          20
Total          60


- The counters would be used to protect the Lich's Mirror and optionally other key cards, but really keep 'm to protect your mirror.
- The walls are there to swap with Puca for whatever you like (to bad you can't steal lands, but you can use the Dominus for that (!!!)), the walls won't attack you and you'll return them to your deck anyway   Oh and, good luck in paying the upkeep for your Illusionary Wall Mr Opponent

Your goal is to stall the game as long as possible, just keep playing lands and whenever you want, throw an X-burn at them which can be forked (as can your counters in counter wars). If you would lose the game, just ensure you've got a shitload of mana in your mana pool (tap all out) - then when you draw your seven new cards, hope you've got another X burn.

Maybe more X burn is needed, but definitly prefer instant (so if your opponent kills you in his turn, you reset and kill him ). And if you don't grab an X burn, just grab a Lich mirror (or fabricate one) and try again!.

What ya think? Conjured this up in 10 minutes, so definitly needs tweaking, but I see potential. Will try this for my fun multiplayer games anyway
