And another question, if nincada were to evolve, would i be able to control both Shedinja and Ninjask?

I'm not the GM, so I can't make an official call on this, but I would say for the purposes of this particular environment that Shedinja would just be an extension of your character. That is, the Shedinja would move and attack as the Ninjask did, while still having its own moves and abilities, but the Shedinja would not really have any personality of its own. By all technicalities, your Ninjask should be able to direct it like a simple creature, since it is an extension of himself.

Maybe that isn't the case here, I don't know. I just find it a funny circumstance that your Ninjask could be constantly trailed by the ghostly Shedinja, made even funnier if the Ninjask sees that as completely normal and doesn't understand why everyone's freaking out about it.
