The official Digimon Card portal updated early this morning with the next set of Tamer Battle and Tamer Meet promotional cards.

Beginning in October, tournament winners will receive an alternate artwork Were Garurumon print from Starter Deck 2: Cocytus Blue. This Were Garurumon is identical to the Starter Deck version in effect and card number. The previous prize card was an alternate print of Metal Greymon.

Meanwhile the Tamer Meet shop events for October will feature a new Option Card, “A New World”, as the participation prize. Tamer Meets are more casual-oriented events than the competitive Tamer Battles, with an emphasis on having fun over competing to be the best. They consist of 2 hours of free battle participation, rather than a tournament structure.

Main Effect[Main] If you have a “Tachikawa Mimi”, by placing 1 “Palmon” from your hand without paying the cost, return your “Tachikawa Mimi” to your hand.
Security Effect[Security] Add this card to your hand.

This card is the first of several to be adapted from popular Adventure, 02, tri., and Last Evolution Kizuna anime scenes voted in by fans through Digimon Web. The artwork is pulled directly from episode 54 of the 1999 Digimon Adventure TV anime, which is why the Chosen Children in the artwork do not use their reboot designs.

“A New World” creates an interesting combo for the Green deck; it allows a Green player to use Palmon‘s on-place effect for 0 cost, and (if they have enough Memory) use Mimi‘s Rest effect twice in one turn by first Resting her to activate it, then playing A New World to bounce her back to hand and play her again. This is easiest to do if Mimi was already in play when the turn began, and it requires the opponent to have given the Green player at least 4 Memory to pull off.

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.
