I tried to use Space Dragster in Synchrons today. You can keep on making additional Formula Synchrons beyond the ones you usually need to make Stardust Warrior of Quasar/Sirf. Rush Warrior in the Graveyard allows you to keep recycling Formula Synchron and Level Eater is almost always available for Synchro fodder. With Hyper Liberian, it’s not hard to keep on drawing cards. The biggest problem with Space Dragster is that it has protection for Tuner monsters but not for itself. You might want to run something to protect Spell/Trap cards from destruction but having something like Stardust Dragon or Sifr works too. I can imagine this card working well in Resonators too because it gives you a quick access to a Level 1 Tuner to make Abyss or for double tuning into RDA Tyrant/Nova/King Calamity. Fun little card with potential IMO.
