At the start of your upkeep, choose one —
Create a 1/1 Blue Tinker Toy artifact creature
token that enters the battlefield with a flying
counter; or create a 1/1 Red Tinker Toy artifact creature token that enters the battlefield with a
Haste counter; or create a 1/1 White Tinker Toy artifact creature token that enters the battlefield
