From the official Japanese Twitter account, one of two Secret Rares in BT1: NEW EVOLUTION. This Virus-attribute Metal Greymon is actually the original design created for the 1997 virtual pets; the orange Vaccine-attribute one that appeared in Digimon Adventure was created for the anime. The alternate artwork revealed today reuses the artwork and card layout from the Metal Greymon printed in the first booster set of the 1999 Digital Monster Card Game, which in Japan was actually a well-designed and popular TCG.

This effect appears to be designed with the new Tamer Cards in mind, which ensure the opponent will always have at least 3 Memory on their turn. These new cards allow you to play around that a bit, gaining extra Memory that allows you to play more cards and ideally manipulate the gauge so that it ends exactly on the opponent’s 1. That 1 Memory then jumps up to 4 thanks to these effects—the opponent ends up with 1 more Memory than if their Tamer Card had resolved, but you get to have 3 more Memory during your turn, a positive exchange for you.

Booster 1 launches in Japan May 15th, 2020.
In a livestream aired at 3 AM Pacific Standard Time, Bandai Namco revealed several upcoming promotional cards for the 2020 Digimon Card Game, and also showed a 2020 concept trailer for the entire Digimon franchise that revealed two more Digimon effects from the upcoming TCG. Bandai also opened an official Digimon Card Game Twitter account shortly before the livestream aired, where it gave us our first look at the product packaging for the Starter Decks “Gaia Red,” “Cocytus Blue,” and “Heaven’s Yellow.” The header for the Twitter account–which also appears as the illustration for the game’s first promo pack–suggests V-mon, Liollmon, Kokuwamon, Betamon, Tentomon, Dracomon, Plotmon, Goblimon, Pico Devimon, Patamon, and Guilmon, are all coming to the card game.
The Starter Decks are on-schedule to launch in April at 500 yen per deck. The packaging states that the game is for ages 9-and-up, which is noticeably higher than the current standard for TCGs: Yu-Gi-Oh!, Pokémon, Buddyfight, and Cardfight!! Vanguard are all recommended for children 6-and-up.
