A Riftbound master set is every printing you can pull from a set's packs: one of every numbered card, the alternate arts, the foil of each Common and Uncommon, and the overnumbered cards. In Origins that is 509 cards. Here is what each tier adds.
Ask a Riftbound collector what "done" means and the answer usually depends on how far they want to go. Some stop once they have one of every numbered card. Others will not rest until the overnumbered and signed cards are in the binder too. Both are right, they are just building different tiers.
On Binder Foundry, a Riftbound set binder is built around the same three-tier ladder as Pokémon: pick a tier and your binder rebuilds around it, so the gaps you see are exactly the cards you still need. The tier names carry over, but do not assume they mean the same thing they mean for Pokémon. Riftbound has no reverse holos and no evolution lines. It has domains, champions, and its own finish and rarity structure, so a few of the tiers land differently.
Here is how the tiers stack up on a real Riftbound set, such as Origins.
The Complete Set is where most collectors start: one printing of every numbered card in the release, plus the Runes and tokens printed with the set. Where a card exists in more than one printing, Complete keeps the standard one. It also takes the alternate arts: cards from the set with new artwork, marked with a letter after the number, like 019a. Sets that print Special cards, numbered SP1, SP2 and on, add those here too. In Origins, Complete is 328 cards: 298 numbered cards (88 Common, 84 Uncommon, 84 Rare and 42 Epic) and 30 alternate arts.
The Master Set adds every other printing you can pull from a pack: the foil of each Common and Uncommon, and the overnumbered cards, numbered above the set’s printed total. In Origins that is 169 foils and 12 overnumbered cards on top of Complete, 509 cards in all. This is where most of a set’s value sits.
Some cards go further still. Signed cards carry the artist’s signature over the same illustration, and they take you to the top of the ladder, the Grand master set. In Origins, that is 12 Signed cards on top of the 509 in Master. A set with no Signed cards or promos yet still shows Grand master, holding the same cards as Master. A Master Set is already a serious binder by most standards. Grand master is for collectors who want every print.
Promos work the same way they do for Pokémon: Grand master includes Riftbound’s tournament and event exclusives, including the metal-plated promo prints. On a Complete or Master binder you can switch on the Signed cards and “Include promos” as add-ons instead.
There is no correct tier, only the one that matches your time, budget and patience.
