## Description

Released in 2020 as part of the Starter Deck Cocytus Blue, the Kaiser Nail (ST2-15) serves as a pivotal Blue Option card within the Digimon Card Game. Designed for players building decks centered around the blue color identity, this card provides a crucial mechanism for accelerating your game plan. As a Card Type Option with a Play Cost of 4, it offers a straightforward yet powerful effect that helps bridge the gap between your current board state and your ultimate strategies. The core utility of Kaiser Nail lies in its ability to manipulate the digivolution process. The card allows a player to choose one Digimon digivolution card placed under one of their Digimon and play it onto the board without paying its cost. This effect can also be activated from your Security stack, providing a safety net against opponent attacks. By bypassing the standard cost requirements, this card enables collectors and players to deploy higher-cost Digimon earlier in the turn, potentially turning the tide of battle before the opponent can react. For collectors, this card represents a key component of the early Digimon Card Game ecosystem. The ST2 code signifies its origin in the first wave of starter decks, which introduced many fundamental mechanics to the community. The Starter Deck Cocytus Blue is known for its cohesive blue-themed strategy, and Kaiser Nail fits seamlessly into this design philosophy. Whether you are completing a set of early starter cards or looking to understand the foundational options of the game, ST2-15 offers a clear example of how early game balance was approached. The Kaiser Nail card remains a recognizable piece of Digimon Card Game history, reflecting the strategic depth that has kept the community engaged since its inception. Its simple yet effective rules text makes it an excellent reference point for new players learning the nuances of the game, while long-time collectors appreciate its role in the iconic Starter Deck Cocytus Blue release.
