it defined overcentralization without ever being considered for a ban. Every calc was pretty much made with it in mind, it nerfed entire types.Stealth is IMO obviously the best attack,we could even say that all Gen 4 revolved around it.
It's lack of usefulness is just GameFreak's way of letting us know, "Yeah, Spore is great, but we hate you all so no one gets to use it."I vote for Spore. If more Pokemon could actually learn this move, I think that it would become extremely popular and have a major impact on the metagame. Unfortunately, Spore's usefulness is limited by its lack of many viable users.
...One?It's got to be U-Turn... Look at how many moves in 5th gen are emulating it's effect just with different typing.
