Thanks for the info! I've realized that some are not that "worth it" if you're already strong in the game, but certain one's do give you the tunics and Epona which can't be obtained anywhere else... The Zelda games are my favorites, so I think I'll end up getting these cards just to truly have the game finished 100%... and maybe in future play throughs they'll be useful anyway. On another note, more than a month in of playing almost every day and I'm only just now finding the forgotten temple?! I never saw these massive ruins before... It just keeps surprising me every time.
