An oversized version of Morpeko VSTAR joined as a single image which can be put in the First Partner binder. This is the best use of the oversized cards to me, as it matches the exact size of how the joined V-UNION pieces look. Selected items are only available for delivery via the Royal Mail 48® service and other items are available for delivery using this service for a charge. The V-Union mechanic was introduced to the trading card game in the Autumn of 2021. It sees four regular sized Pokémon cards combining together to form a Jumbo-sized V-Union card. V-Union cards have high HP (Hit Points) and special powers that can inflict high damage to your opponent. However, they can only be used once during a game so the player needs to choose carefully when to play their card.
