Generally in these, the location of the relic hit(s) is obvious, just look for the thicker card(s). But the type or set it is from isn't. But this time, there was one that defied those rules.
Which contains eight relics for the price of one.
The only problem is that because of this card, there were slightly fewer than 250 cards in the cube. I guess 'packs with a special insert may contain fewer cards' also applies to repacks.
