Requires Reborn Tengu on the field, Genex Ally birdman, Mist Valley Falcon, and Divine Wind of Mist Valley in hand

The one time I pulled this one off was against six sams. The only reason I didn't have divine wind on the field when I bounced tengu for birdman was because I did that part my first turn, then for my second turn drew divine wind

Here's what I did (my opponent already had no monsters and no f/d as I had warninged his kageki and all the backrow he had was gateway):

Bounce Tengu for Genex Ally Birdman
Eff Tengu, SS #2
Normal summon Mist Valley Falcon
Activate Divine Wind of Mist Valley
Attack directly with tengu, birdman, and falcon (5600 damage so far)
Falcon eff, bounce tengu
eff tengu, SS #3
eff divine wind, SS some random MV with at least 700 ATK
attack with tengu and other random mist valley (up to 9300 damage, depending on what you summon)
