A: In the vast majority of cases, you cannot win if you have Creepers not specifically required by the goal.
Exceptions:
• Do your extraneous Creepers say that they keep you from winning? (Almost all Creepers do, but if they don’t then go for it.)
• Is there a Rule in play that lets you win even if you have Creepers? (There are a couple of these, depending on which versions you have.)
• In Batman Fluxx, if the Goal requires a Villain, Villains don’t prevent you from winning. However, if the Goal does NOT require a Villain, then Villains ANYWHERE prevent you from winning.
• In Nature Fluxx (aka EcoFluxx) all Creepers prevent everyone from winning, regardless of who has them.
