At the beginning of your upkeep, if you control no Thopters other than Thopter Assembly, return Thopter Assembly to its owner's hand and create five 1/1 colorless Thopter artifact creature tokens with flying.
6/1/2011 The triggered ability looks for any permanent you control with the creature type Thopter, not just the Thopter tokens previously created by a Thopter Assembly.
