Shimsham is a tribal deck that focuses on a pretty much completely unused (until now) tribe: Shamans.

Shamans at first might appear to be a "wtf?" choice, but just consider that all of the following cards are, in addition to their other types, shamans.

Sakura-Tribe Elder, Eternal Witness, Troll Ascetic, Doran the Siege Tower, Vexing Shusher, Rakdos Guildmage, Bloodline Shaman, Masked Admirer's, Nezumi Shortfang, Bosk Banneret, Burning-Tree Shaman, Emberwilde Augur, Essence Warden, Gorilla Shaman, Loaming Shaman, Nullmage Shepherd, and Viridian Shaman. (plus every changeling spell)

The main two reasons to run Shamans though, are the Kinship cards, Leaf-Crowned Elder and Wolf-Skull Shaman. Between these two cards you can generate an absolute Sh*tton of critters for free in a relatively short time frame. With StE and Banneret accelerating all your spells, you can play these out very quickly.

I'm basing this off a completely untuned but still way more successful than it should be extended list that follows the same principle.

4x Sakura-Tribe Elder
4x Bosk Banneret
4x Chrome Mox

Lands
3x Windswept Heath
3x Wooded Foothills
2x Forest
1x Plains
1x Mountain
1x Swamp
2x Bayou
1x Taiga
1x Savannah
1x Badlands

Sideboard
3x Krosan Grip
4x Thorn of Amethyst
4x Gaddock Teeg
4x Pyroclasm

There are 18 lands + 4 mox + 4 ste + 4 banneret. There are a lot of playable shamans that aren't in this list, and I'm not sure that their exclusion is the correct choice. Nullmage Shepherd looks weird, but with all the critters you get out with this deck, it's pretty amazing at dealing with any amount of art/enchant in staxish style builds, and grips are there for things like enchantress and c/b and plague.

This is just a rough sketch of what this deck should probably end up looking like long term, but its got a lot of card advantage and a lot of inherently strong cards in it.

Other cards that I can see someone making a very good argument for including:
Sensei's Divining Top
Aether Vial
Umezawa's Jitte/Sword of Fire and Ice/Sword of Light and Shadow
Masked Admirers
Viridian Shaman
Rage Forger
Thoughtseize/Duress
Orim's Chant
Swords to Plowshares
Troll Ascetic

I'd love to hear some other peoples' thoughts on this concept.
