[Meta thread] Lord Windos' PokeRole Adventure : Celadon City Vandels

Is good to see you are teaching Reiner to hang in that Mew situation, but you think it's a good idea to him get a Mewnium Z? Mew it's already a powerful being, and if they do any wrong move...the results might be devastated.

As long as Mew disagrees with using Genesis Supernova, there's a 0% chance of the move being usable.  It's up to Reiner to convince Mew the Z-move is actually worth using before there's any risk involved.
