Like a bullet train in the sky Jun 15th
Dave (from The Energon Hustlers) has been hard at work on the upcoming set Turbo Revving Old Punks: Phase 1. With additional play testing from members of both The Ark and Team Bayformers, it's shaping up to be a great looking set. Teletraan I was given a spoiler to show off, so I'll let Dave introduce it.

"Well here it is - a fan fave character who certainly didn't get his dues from WOTC - Astrotrain! We have enjoyed working on this one - it really takes him to another level of power - enabling OA fast and also making his flips valuable. We hope you like it!"

This card really invokes the feel of Astrotrain's Siege toy, loading him up with all those weapons and making him into a walking arsenal.

Turbo Revving Old Punks: Phase 1 is getting it's final fit and is aiming for a July 5th release!
ATP-4 added, BFA updated Jun 15th
ATP-4 is fully added to Teletraan I now, and ready for you to build decks with. Additionally, BFA has been updated with OCTGN IDs, and can be played on OCTGN using Jihen's OCTGN set.
