So here is a question, I know there is a rules section but well for one this card is not released and subject to change and there really is no FAQ or rules to clarify the final say.
But back to Ion tokens and Juno's ability?
So Ion tokens force a white 1 straight maneuver. Juno can increase the speed or decrease the speed to a minimum of 1 (assuming there is a maneuver template). So can Junot make it a White 2 straight instead?
