This clever interaction leverages Emissary Green's attack trigger to command a unanimous "profit" vote, seeding the battlefield with a sudden swarm of tokens. Because Elspeth, Storm Slayer doubles all token creation and Esix, Fractal Bloom steps in to transform those new tokens into copies of a chosen creature, a single combat phase is all it takes to flood the board with copies of Biovisionary. Once you successfully control four or more of them, the end step trigger from Biovisionary cleanly clinches the win.
