Some extra fuel from Fuel Tank is always nice, along with some extra forward thrust distance with Propel. Rain of Fire is a very good card for carrying a lot of Momentum over long distances. Hyper Boost is there to restore some Booster Fuel when you start running low, and Survival is there for a Quick Escape, or to get a quick heal then to rush back in, while also once again, triggering Rain of Fire allowing you to push further.
