More about Riftbound — Origins: Proving Grounds

Proving Grounds (OGS) is the companion set to Riftbound Origins, released alongside it on 31 October 2025 and built around the starter decks rather than boosters. Nothing from it is in stock with us at the moment.

Companion sets like this one exist to solve a specific problem: a brand-new card game needs a way for two people to sit down and play without anyone knowing the rules. Proving Grounds was that, and it's where most UK Riftbound players started, which is why it's harder to find now than the boosters were.

For anyone coming to the game fresh, the structure is worth knowing. Riftbound runs four sets a year, each 14-card pack has a foil slot, and above the standard rarities sit Alternate Art cards and the Overnumbered secrets, including signed Signature versions at genuinely tiny pull rates.

In stock now: the wider Riftbound range. Coming releases are in pre-orders, and anything that lands appears in new in.
