Piracy: ꜱᴀɪʟ ᴛʜᴇ ʜɪɢʜ ꜱᴇᴀꜱ

@sleepybisexual Aside from what lvxferre said, there's also Stealth Rock with very ineffective way of removing it because of ghost types, random 120 base power moves and the physical/special split essentially buffing the coverage of offensive pokemon (Gengars can actually use Ghost type moves). Essentially the gen that made dragons overpowered. I guess you can say these are all subtle. Gen 6 onwards just made it more blatant with gimmicks like mega-evolutions, z-moves and terrain.
