The bane of collectors.
When you're one item away from completing a set, but you can't find it no matter how hard you look in store shelves or how many packs you buy.
Person A: You got to help me!
Person B: What's wrong?
Person A: You know how I need only more card to complete my set, right?
Well, I opened ten 5-card blind packs, and I didn't get it!
Person A: Looks like you're suffering from the last item curse.
