Combo Myr Battlesphere +Mechanized Production +Time Warp +Esix, Fractal Bloom
Have Esix and Mechanized Production in play. Cast Myr Battlesphere. Using Esix' ability have the Myr tokens enter the battlefield as copies of Myr Battlesphere. Each of those copies creates 4 Myr tokens, for a total of 16 Myr tokens. Cast Time Warp to take an extra turn. End your turn, and you win on the next upkeep. Note, Time Warp is not absolutely necessary, but you will need some way to ensure all Mechanized Production and most of your Myr survive til your next upkeep. Taking an extra turn is an easy way to guarantee that.
