I guess I should answer my own question, too.
I currently have seven decks in paper. The weakest is the
Omnath, Locus of Mana deck on my profile. Out of 10, I'd give it a 4. It has good synergies, but very little interaction and protection. It's mostly meant for playing against stuff like precons.
The best deck I have is probably my
Ezuri, Renegade Leader deck, though between it and my
Scion of the Ur-Dragon deck, I'm not honestly sure. Ezuri is as optimized as I can make it, down to
Gaea's Cradle and what not. The Scion deck isn't running original duals, but it's running a full set of shocks and fetches, as well as good mana rocks like
Mox Diamond and
Mana Crypt. I'd give them both 8s because they're not cEDH, but they're definitely at the top of casual play. (I also have a Thrasios and Silas deck that's pretty decent, but the main idea is to win with myr, so I'd put it below the other two.)
When I play in a store, I usually bring Scion and Ezuri because they're my favorites, along with one or two weaker decks. I brought my Momir Vig cEDH deck for a while, but it usually just sat around.
