Was wondering about using Infernal Contract.

Draw 4, lose 1/2 your life rounded up.

I must admit I'm not a tier one player but it doesn't seem that it would be that much of a drawback to include one.  I realize that you would, in most cases, need to use one of 7 cards (lotus/rituals) to get it off but getting 4 new cards to help things churning sounds good to me.  The wording on it that doesn't allow it to be misdirected is a plus too.

I make a bunch of bad moves pretty much every game.  My most memorial bad however was done by an opponent at Gen-Con.
Back in '97 (I think) at the vintage tournament, I was playing a very very simple deck based on Juggernauts and Juzams with Disks to clear things up.

I had dropped a quick juzam on the board and had him down to low life. 

He dropped a moat.

I lost some life and dropped a disk.

Instead of disenchanting my disk he decided to tap out playing a second moat.

*doh*
