This is a Fat Stack "decklist" built from all the commons I have of cards from the Khans block:
Dragons of Tarkir
Fate Reforged
Khans of Tarkir

The mana curve is almost perfect, and the color assortment is on point as well. There's only 3 mill cards, and for the search effects they only search up lands, making it so you never have to shuffle the main stack, only the lands stack (the sideboard). Included 5 evolving wilds for more fixing.

Synergies are unknown. Theoretically they should all synergize with similar color combinations in the block, but since this block had both two-color and three-color "clans" it makes the broader synergies more, well, synergistic. I think this block could potentially be the "perfect" block to Fat Stack.

Here's the 50 card lands deck:
1 Bloodfell Caves
1 Blossoming Sands
1 Dismal Backwater
5 Evolving Wilds
7 Forest
7 Island
1 Jungle Hollow
7 Mountain
7 Plains
1 Rugged Highlands
1 Scoured Barrens
7 Swamp
1 Swiftwater Cliffs
1 Thornwood Falls
1 Tranquil Cove
1 Wind-Scarred Crag
