Best Moveset For A Shedinja?

[Perfect Chaos]

Damnit Alu, you're so good and helpful in TCG, why can't you be like that for Pokemon

Anyways, Solarbeam is mainly used on Sunnybeamers (Sunny Day+Solarbeam), so that's a no.

Sandstorm will literally kill your entire team (since it'll affect all your Pokemon and it lasts 5 turns), so that also is a no.

I'd say stick with Shadow Ball as one of your main attacks. They all get STAB from it and with Swords Dance, it'll leave a pretty big dent on most Pokemon.

Oh and one last thing:

but because I have a hard-on for undead demon insects, I'll help you with Team Shedinja as best as I can.

Now THAT'S disturbing (moreso than me orgasming at getting a Fiend structure deck Blade )

Because I keep up to date with yugimons!

Sandstorm damages my Ninjas? I thought only Super Effective attacks could~? Lolz?

So just fuck the Return and throw on a Shadow Ball~?

Shadow Ball is fine. And yeah, Sandstorm (and Hail) kills your team - you're not immune to weather effects. Nor are you immune to stauses and the like: Poison makes Sheddy cry. Only attacks that directly damage you fall under Wonder Guard's defense. Not sure about OHKO moves, but few people really use them anyway.

THAT is debatable...

Now, as for Shedinja...

Solarbeam = definitely no. Trust me, Jay, Shedinja's special stats are so bad, it's not even funny. Shedinja can learn Sunny Day, but even that doesn't make the move worthwhile.

Aerial Ace = maybe. Shedinja's got good attack, and Aerial Ace never misses. Still, I'm not really sure how useful it'd be effective-wise, so... I dunno. You make the call.

Sandstorm = definitely no. As has already been said, weather effects can kill Shedinja, and even if they couldn't, it wouldn't matter - since Sandstorm is technically a Rock attack, it would bring Shedinja down anyway.

Return = maybe. It can be almost as strong as Hyper Beam without needing a recharge, but if you have Slash and Hyper Beam already, you won't need it.

P.S. OHKO moves don't work on Shedinja.
