One area of the game that felt like it could use some true expansion was the Sensei card pool. However, we did not want to just go creating new Sensei cards that might end up overpowered or underpowered, so we looked to the GT card pool and chose two that would carry over well for what they should accomplish into the Retro format. Of course, we tweaked them slightly to try and make them more easily used and approachable.The first Sensei should be of no surprise, as it was the most popular to be used of the GT Sensei cards.
