Battle of Omni, released in August 2021, stands as a landmark expansion in the Digimon Card Game's early era. This set delivers powerful evolution lines, impactful tactics, and some of the most sought-after promotional variants in the game's history. The presence of multiple Omnimon versions and tournament reward cards has created a fascinating secondary market with massive price disparities between standard releases and exclusive variants.
Omnimon (Serial Numbered)
The crown jewel of Battle of Omni, this serial numbered promotional variant commands over $550, making it one of the most expensive Digimon cards ever printed. Limited serialization creates extreme scarcity, and as the iconic fusion of WarGreymon and MetalGarurumon, Omnimon represents the pinnacle of Digimon collecting. This version's exclusive numbering ensures each copy is unique, driving demand among high-end collectors.
Omnimon (Across Time Box Promo)
Another premium Omnimon variant, this Across Time Box promotional version reaches nearly $91. While more accessible than the serialized edition, this alternate art release was distributed through special box sets, limiting availability significantly. The promotional distinction and striking artwork make it a centerpiece for collectors seeking the set's defining Digimon without reaching for the serialized version.
Greymon - BT5-010 (Premier TO Event June 2021)
Tournament organizer promos carry immense value due to their restricted distribution, and this Greymon exemplifies that trend at over $73. Given exclusively to tournament organizers during the June 2021 Premier Events, this uncommon card became extraordinarily rare. As an essential evolution stage leading to WarGreymon and ultimately Omnimon, collectors prize this promotional variant both for scarcity and playability.
Nokia Shiramine (Evolution Cup 2025 Vol. 3 Winner)
Championship winner cards represent the ultimate in exclusivity, and this Nokia Shiramine tamer card from Evolution Cup 2025 Vol. 3 reflects that status at nearly $51. Reserved for tournament champions, these prizes exist in minimal quantities. Tamer cards provide crucial support effects in competitive play, making this simultaneously a trophy and a functional game piece.
Arata Sanada (Evolution Cup 2025 Vol. 2)
Another Evolution Cup exclusive, this Arata Sanada tamer from Vol. 2 commands approximately $40. While slightly more available than winner-exclusive cards, Evolution Cup participation rewards remain highly limited. The character's connection to Digimon Story: Cyber Sleuth adds collector appeal beyond the card's competitive utility.
Koromon - BT5-001 (Premier TO Event June 2021)
Matching its evolved form Greymon, this Koromon TO promo sits at nearly $25. Despite being a simple in-training level Digimon, the tournament organizer exclusivity transforms this common evolutionary stage into a premium collectible. Completing promotional evolution chains drives demand among completionists.
Revive From the Darkness! (Championship 25-26 Tamers Pack Season 1)
Championship Tamers Pack rewards maintain consistent value, with this uncommon option card reaching over $14. These seasonal tournament rewards create natural scarcity while providing competitive players access to strategic options. The resurrection theme fits multiple deck archetypes, sustaining long-term interest.
Omnimon Zwart Defeat (Alternate Art)
The most affordable chase card on this list at approximately $8, this secret rare alternate art showcases Omnimon's dark counterpart. Secret rares from standard booster distribution remain accessible compared to promotional variants, though the striking artwork and powerful in-game effects make this version highly desirable for players and collectors alike.
Battle of Omni demonstrates how promotional distribution dramatically impacts Digimon card values. While the set's standard secret rares remain reasonably priced, tournament rewards and special box promos command premiums ranging from modest to extraordinary. The $550 gap between the most and least expensive cards on this list reflects the Digimon community's willingness to pay for exclusivity and nostalgia.
