Starter Deck 01: Gaia Red was one of the inaugural releases for the Digimon Card Game, launching in January 2020 and introducing players to the iconic Agumon evolution line. Built around the classic red Greymon family, the deck provided a straightforward and accessible entry point into the game while establishing the foundational mechanics of Digimon's unique Digivolution system. While the base cards in the set are widely available and budget-friendly, it is the promotional and stamped variants tied to 2021 championship events that drive the most excitement — and the highest price tags — among collectors.
Agumon - ST1-03 (2021 Championship Online Regional) [Online Champion]

This promo variant of the classic Agumon is the crown jewel of the set, awarded exclusively to Online Regional Championship participants or winners in 2021. Its extreme scarcity and direct tie to competitive history make it one of the most sought-after Digimon cards overall, commanding well over $100 on the secondary market.
WarGreymon (2021 Championship Finals Event Pack Alt-Art Gold Stamp Set)
The apex of the Agumon evolution line, this alt-art WarGreymon features a gold stamp and stunning alternate artwork, distributed through the prestigious 2021 Championship Finals Event Pack. Its Super Rare status combined with the gold stamp treatment makes it a trophy piece for serious collectors.
Greymon (ST-11 Special Entry Pack)
This Greymon promo, distributed through the ST-11 Special Entry Pack, offers a more accessible but still desirable variant for fans of the classic evolution line. Its limited distribution channel keeps supply tight enough to sustain a meaningful premium over base versions.
Gaia Force (2021 Championship Finals Tamer's Evolution Pack)
WarGreymon's signature finishing move appears here in a championship-stamped version tied to the 2021 Finals Tamer's Evolution Pack. Even at the Uncommon rarity level, the event-exclusive distribution makes this option card a collectible worth tracking down.
Agumon - ST1-03 (July Evolution Cup 2021 Stamped)
Another stamped Agumon variant, this time from the July 2021 Evolution Cup, represents a more attainable entry into the world of tournament promos. It carries the competitive pedigree of an event stamp at a price point that still appeals to budget-conscious collectors.
Price trends in Starter Deck 01: Gaia Red are almost entirely driven by promotional and event-stamped variants rather than the base set cards, which remain widely available and inexpensive. The gap between the top promo — worth over $127 — and the fifth-ranked card at under $5 illustrates just how sharply scarcity tied to competitive events inflates value. As the Digimon Card Game continues to grow in popularity, demand for early championship promos from 2021 is likely to remain strong, particularly for iconic Digimon like Agumon and WarGreymon.
