During MetaZoo’s 2023 year of in-person sanctioned TCG competition events; named the 2023 Tower Events, there were different promo cards given to attendees, players, and top-placing players.
The cards available from each event depict the building of its specific aura type’s Tower, alongside a Beastie with that same aura type growing from just a baby, to full adulthood. And I kinda love it.
The ‘… Building Begins” promos were limited to a print run close to the number of players in the competition.
The ‘… Building Continues” promos were limited to a print run of 32, and given to the top 32 players.
The ‘… Building Complete” promos were limited to a print run of 16, and given to the top 16 players.
