MTGO
Now with a commander variant Momir Vig's Mad Experiment
regularly closes games with a board full of 23/23's and 80-140+ life
the singleton Mirror-Mad Phantasm is an awesome one-off mill
Increasing Confusion puts your extra mana to use, and digs for stall power, and even see's occasional use as a win-con (milling the opponent)
Gnaw to the Bone is what makes all the magic possible, extending the game well beyond what your opponent expected to deal with (especially when they get within 1 to 3 points of health to winning)
Memory's Journey is a last resort reset giving you an extra turn if your Laboratory Maniac sees removal
Dawntreader Elk and Armored Skaab both provide good early game blockers as well as card advantage and creature bodies for your graveyard
Mindshrieker can be amazing on the defensive, standing in front of all but the most evasive of attackers, and activating its ability after blockers have been declared, and netting a topdeck Ghoultree feels epic, and has made more than one opponent decry "unfair!" and walk away
Deranged Assistant usually makes any spell cast with his mana more effective by putting one more creature in the yard
Think Twice just one, so make it count and choose your timing wisely for the endgame
and usually with two casts of Artful Dodge on a Boneyard Wurm , Ghoultree , or Splinterfright will make any opponent concede before the combat step
and after all that you might think you can cut back a few cards to get back to 60, but the 68 gives you one or two extra turns that make alot of difference
