Sealed product or singles?
Packs are a lottery ticket with a floor; singles are the thing you actually wanted. The honest math on which to buy.
Every TCG buyer eventually faces the fork: buy sealed product (boxes, packs, bundles) or buy the specific cards as singles. The honest answer is that they are different purchases wearing the same hobby's clothes — one buys chance and ritual, the other buys certainty. Pricing them against each other properly means valuing both the gamble and the goods.
Expected value, with a catch
The standard analysis is expected value: what the average box's contents resell for versus the box's price. In a healthy market, singles prices adjust until boxes hover near break-even — slightly above when gambling demand is hot, slightly below when it is not. The catch: expected value assumes you can and will sell what you pull. If you keep everything, your "value" is enjoyment, and no chart prices that.
What sealed really sells
Sealed product carries a premium that is not about contents: the experience of opening, the shot at a chase card at pull rarity, and — for complete sets held sealed — collectible value in its own right. That premium fluctuates with the game's heat, which makes sealed a sentiment asset as much as a card source. In a young game like Riftbound, sealed also carries discovery risk in both directions: nobody is certain yet how supply and demand settle.
When singles win, and when packs do
One more asymmetry: singles keep you on the metagame's treadmill — deck prices move with results, which is what this site charts. Sealed insulates you from deck-level swings and exposes you to game-level ones. Choose the risk you actually want.
