This has been a week for pleasingly quirky Extended decks.
First, I direct you to this week's Top Decks article from Michael J, where he highlights Scott Honigmann's PTQ-winning mono-white control deck as well as Bradley Carpenter's quite surprising Lightning Zoo. Really, go look, especially for Lightning Zoo.
Second, it's usually worth taking a look through each week's Decks of the Week for interesting standouts. Amidst a bunch of the expected decks, I spied this build from an online PE on the ninth (click through to the extended for the deck list):

This has some features of the now-standard black-green midrange frame, with some mix of Eternal Witness, Sakura-Tribe Elder, and Kitchen Finks. This is seasoned, however, with a host of intriguing card choices, including double Wickerbough Elder, triple Gargadon, a single Siege-Gang Commander, quadruple Utopia Sprawl, and quadruple Primal Command.
The multiple Primal Commands are a call back to midrange decks from the Onslaught-Mirrodin and Mirrodin-Kamigawa periods of Standard, taking the place of Plow Under while also being a house against Zoo and Burn decks and letting the user tutor up utility or power creatures as needed. I'd have to test the deck to really get a feel for what it can do, but there are many synergies in the build, such as the ability of a suspended Gargadon sac a Finks to get some extra life in the burn matchup, or the ability to Command for Witness, then Witness back Command, and so on and so forth.
Neat. I like these outliers that highlight the fact that some imagination has a place in the current Extended environment.
