Theme Boosters make a return with Kaldheim. These are great as an intro-level product or for more casual players looking to grab a bunch of cards that match a particular color or theme. Just like Set Boosters, Theme Boosters may contain some of the same 20 special cards only available in a few places. Each booster contains 33-34 commons/uncommons and 1-2 rares/mythic rares. Theme Boosters can also contain uncommon showcase cards!
