Shedinja - Huh?!

[Always and Never]

I've never trained a Shedinja, so I have no idea why this would be. Why does Shedinja always have 1 HP? I mean, what about putting 252 HP EVs with a 31 IV? How come it is always "1"?

Yeah, which is why it sucks, because any Fire, Flying, Rock, Ghost, or Dark type move OHKO's it, and those are common types.

Also Sandstorm, Hail, Spikes, Stealth Rock, and any status condition that causes damage destroys Sheddy

But it had 1HP to counter the fact it's ability makes it unstoppable vs certain pokemon, so they make sure that if it can hit Sheddy, then Sheddy dies, dont know why exactly
