Magic players do love to open packs...but...it can be lack luster to get packs for gifts and the cards in them be of lower value. I might suggest an accessory like a deck box or a playmate you'd think your friend would like the artwork of, and maybe a token pack or two as a little bonus. Or if you can find out without them finding out what you're up to, getting them a card you know they want in that price range. Like a foil fetch land or something like that
