Hi,

A store is running a sealed GPT for Brasil this saturday, but it says he is going to use the Gatecrash Prerelease guild packs. I am not sure if that is posible, being a competitive format and those packs being just for the prerelease experience, so I wanted to check first for an official answer.

Thanks

Official answer: stores must follow the instructions on the fact sheet they receive for GP Trials.

Thanks! - Scott Marshall
