The "Prologue of the Destruction Swordman" graveyard effect protection from battle or card effect not working. mainly with Buster Blader, the Destruction Swordmaster.

Prologue states it protects Destruction Sword cards from battle or card effect.
It's important to note, Buster Whelp of the Destruction Swordsman does consider Buster Blader, the Destruction Swordmaster a destruction sword card.

A fix would be nice. :)

Thank you!
