Some foreign teams partnered with local ones to participate in the league, including Evil Geniuses with SlayerS under the name SlayerS-EG, Team Liquid (prior to participating on their own) with Old Generations under oGsTL, and Quantic Gaming with StarTale under StarTaleQ.

Of these, Incredible Miracle, StarTale, MVP, Prime, and EG-Liquid, a combination of Evil Geniuses and Team Liquid, moved to the competing StarCraft II Proleague, some before and some after the dissolution of the GSTL.
