I only need 1 sticker to complete the album but I have gold stickers my friends need. I have enough stickers to turn in for big vault to get last sticker but will I lose all the gold stickers? I am also about to get the PEg-e wild card. Would it be best to go ahead and trade in vault for last wild card then finish Peg-e? I hate to lose everything my friends need but I hate to lose the opportunity to get extra dice with vault. I guess not sure how it works when you finish the sticker album via vault trade early.
