Forum:Generation Shift vs. Fire King Barong

I have seen this in "Rullings" of Fire King Avatar Barong:

"If you activated 'Generation Shift' destroying a face-up 'Fire King Avatar Barong' you control while you don't have 'Fire King Avatar Barong' in your hand, if you add a "Fire King Avatar Barong" from your Deck to your hand by the effect of "Generation Shift", that "Fire King Avatar Barong" you added to your hand can activate its effect that Special Summons itself from your hand."

his rule is correct? If yes, why? Dark Arisen 11:27, June 25, 2013 (UTC)
