Eh, this product oscillates between ridiculously bad and ridiculously good, with the average case being "not worth your money".

However, I've bought dozens of these that were had 3+ commander decks, Clash Packs (Fetchlands), Planechase decks (Cabal Coffers) or Duel Decks (Demonic Tutor).

For these to be worth it, you really need to know what products had been released in the past few years, and be able to tell which deck is which by the front card of the sealed package.

That said, for the past six months these have been dreadful: Mostly land packs, filled with giveaway deck parts, as well as the last few year worth of intro decks (most of which had nothing of value.)

Some people did say they got lucky and got Challenger deck inclusions while Walking Ballista and Chandra were still pushing up in price.
