During Dallas Regionals this interaction came about, and a ruling had to be made mid tournament. The interaction which needed ruling is as follows:
If I have an Yveltal BKT active with it's Fright Night ability active and a basic energy attached to it, do I get to move the basic energy to one of my Pokemon with an exp. Share attached to it after the Yveltal is knocked out?
The ruling was that you cannot because it acts the same way as the interaction of a Lugia EX with Overflow knocking out a Garbodor with Garbotoxin.
