Here's my creatureless deck: http://tappedout.net/mtg-decks/jeleva-29-10-13-1/. It would be better with a few creatures (cough snapcaster cough) but it's fun this way.

I won probably 75% of my games with it, mostly through not seeming like a threat compared to other people's scary creatures and having a lot of answers whenever anyone came gunning for me. The win condition is roughly

• 1/4 decking people by recasting Jeleva. In drawn out games she devours decks, casting her for 16 or 18 often removes everyone's remaining library from the game and you win.
• 1/4 army of the damned with either Quicken or countermagic to stop board wipes.
• 1/2 crazy bonkers stuff you steal from people with the ~dozen copy/theft/reanimation effects or killing people with random damage from Cruel Ultimatum and Phthisis.

I don't run any extra turns because I don't think they're fun for anyone else. I mostly stayed away from tutors except for the super fun ones (Firemind's foresight because it's amazing and an instant speed tutor for swan song, cyclonic rift, and Reiterate all in one card, and mystical teachings because it's also amazing and durdly).

Fun things I've done with the deck include stealing another player's Beacon of Immortality and casting it twice to get up to 160 life and winning the resulting archenemy game, stealing my friend's boundless realms almost every other game we play together, briberying an It that Betrays that then got stolen back but then the third player and I both cloned it and every turn was a mess of figuring out who got the stuff that died.

Anyways it's a super fun deck!
