>>40865544It's not just that it is based on the most iconic Stealth Bomber, but also that said plane is also literally called the "Spirit" which adds more reasoning behind the Ghost typing.
Also Dragon/Ghost is a far more unique and valuable typing than Dragon/Flying. There are multiple Dragon/Flying Pokemon that you can use in normal and competitive play, but Dragon/Ghost was previously only on Giratina and you're not going to see that being used unless its Ubers or a restricted (i.e shitty) year of VGC.
