Riftbound Origins: Proving Grounds (OGS): the learn-to-play box
Four ready-to-play decks, 24 exclusive cards and everything needed to learn Riftbound with 2 to 4 players.
Origins: Proving Grounds (set code OGS) is Riftbound’s learn-to-play box. Released on October 31, 2025 alongside the Origins set, it has been available in French since May 29, 2026 under the name Premiers Pas.
The box holds four preconstructed decks, each led by a League of Legends champion: Annie, Garen, Lux and Master Yi. The decks are designed for balanced matchups and let 2 to 4 players start battling right out of the box, with guided play materials and deck upgrade suggestions.
On the collecting side, Proving Grounds forms a mini-set of 24 exclusive cards that cannot be found in Origins booster packs. The box also includes an acrylic figure for each of the four champions, with a different expression on each side.
