My friend says each box of yugioh dice contains all 4 super rares. Please inform him he is a moron.

There are only 1-2 SR cards per box.

He's wrong.

But it does depend on the "box".

If "box" means "Gravity Feed" then you are going (usually) to get either 1 or 2 super rares (and if you get 2, I've never seen them duplicate).

If "box" means "case" then you are getting 2 gravity feeds and out of those you will (usually) get 3 super rares (and I've never seen them duplicate).

In either case, the box does not have all 4 super rares.

Shoulda just had him buy a box and find out for himself.
