Four Legacy Champion Decks

Proving Grounds Second Edition introduces four preconstructed decks centred around Champions appearing in Riftbound: Legacy.

• Heimerdinger
• Karma
• Vladimir
• Illaoi

The decks have been designed to create balanced matchups, giving new players an accessible way to learn Riftbound while still offering different Champions and playstyles to explore.

Designed for 2–4 Players

Proving Grounds Second Edition supports games for 2 to 4 players, making it a useful starting point for couples, friends, families and groups learning Riftbound together.

With four decks included in the same box, you do not need every player to purchase a separate starter product before beginning your first games.

Track Your Victories with Chibi Score Trackers

Each featured Champion has a matching custom acrylic Chibi score tracker, with designs for Heimerdinger, Karma, Vladimir and Illaoi.

Four oversized Battlefields and four paper playmats are also included, giving each player the components required to set up their play area.

A Complete Introduction to Riftbound

Proving Grounds is designed as a learn-to-play and introductory Riftbound product. The four balanced decks make it easier to begin playing without first needing to build decks from booster packs or individual cards.

Unlike the original Proving Grounds release, Second Edition does not contain mechanically unique cards that can only be obtained from this box. The cards used in these decks can also be found through normal Riftbound booster products.

Once you're ready to start building your own decks, browse Riftbound singles to find specific cards for upgrades.
