I may be wrong on this, but I and others are playing with Shedinja from lost thunder and when using its ability "Vessel of Life" it also attaches the Nincada it evolved from as well.
The card on the text reads, "Once during your turn (before your attack), you may discard all cards attached to this Pokémon and attach it to one of your Pokémon as a Pokemon Tool Card. If the Pokémon this card is attached to is Knocked Out, your opponent takes 1 fewer Prize card"
From my understanding, this wouldnt be a bug because im referencing older cards like Splash Energy picking up the entire evolution line and cards like AZ picking up the entire evolution line as well even though both cards state "Discard all cards attached to this card". But I have had many people tell me that this shouldnt be the case and PTCGO is in the wrong.
I guess this is also a ruling question in disguise, sorry for the large amount of information but its incredibly important to figure if this is intended or not because it can change the viability of certain decks if so.
