I saw this deck archetype being piloted by one of my favorite Pros, Raphael Levy at the current Standard Pro Tour Kaladesh in Hawaii. I have not seen if it was featured in the deck tech area but basing upon the matchup coverage, I think the decklist looks like this:

Lands
1 Evolving Wilds
7 Mountain
7 Island
1 Geier Reach Sanitarium
4 Wandering Fumarole
4 Spirebluff Canal

Creatures
3 Advanced Stitchwing
4 Stitchwing Skaab
4 Wretched Gryff
4 Prized Amalgam
4 Elder Deep-Fiend

Spells
3 Kozilek’s Return
4 Lightning Axe
4 Cathartic Reunion
2 Tormenting Voice
4 Fiery Temper

We just wait for the final decklist to be posted at the mothership site after the Day Two of the Pro Tour has finished.
