Myr Battlesphere, because Myr are awesome, five bodies are better than one, it's an artifact and it looks like a parody of Legion from Castlevania. It's also a wall of text that no one seems to read till the end. That last sentence is very important. I own six of them currently, but want to start actively hoarding them...
My second Favorite would be Old Fogey.

It gives you information and fulfills three roles.
1) You name a card you would lose to if they had it, thus getting said card out of their hand.
2) You get to see if the way is clear before playing a key spell. Even if you miss you now know what they have in hand and can play around it.
3) You get to sacrifice Academy Rector for free.
Why not run good lands?
Is Children of Korlis better?

I fixed mine. I think what happened is I quoted the post, got up walked away (before submitting) and when I came back FTW1987 had edited their post to add a vote against the card and I didn't notice.

edit: after reading the reasoning behind Whitesun's passage being added (a safety net) I just wanted to mention that ages ago when Phyrexian Processor was a new card, people played it with Crumbling Sanctuary so they could make giant creatures and not worry as much about their life total going low.

All I know is that the last time I tried to play Desecration Demon was in Singleton 100 and they gave me a game loss and made me change my deck in the middle of the event. Which made me salty because it gave me no warnings in Gatherling that the card wasn't allowed.
