Cause Valor is pretty awesome so of course its gonna need a high level friend to get and also they didnt make any new attacm cards during those sets so they would have no use in making a goofy that searches for attacks when they are being replaced by equipments basically.
Things about Set 4 that make me laugh.
i know why they did it i just thought it was funny
Mr. Smee has ten power halved to 5 power making him one of the best lvl2s when considering power in a Dark deck.... Mr. Smee has ten F***ing power lol!
