Shaymin (Sky Forme) LV.X

[Pudls]

Would it be legal for me to have a Grass Pokemon get knocked out, send out regular Basic Shaymin, Level it up and THEN activate Revenge Seed?

 

[ShinjisLover]

Yes, that's legal for you to do, I believe.​

 

[!MajesticSmeargle!]

Yep it's legal, since it's a poke-body it's activated once it's in play.

Unless something stops it like Dialga G lv.X.
