## Description

The X Antibody Proto Form (EX5-070) is a Special Rare Option card from the 2023 Digimon Card Game Promotion series, designed to support strategies centered around the X Antibody trait. As an Option card with a play cost of zero and a White color identity, it offers flexible utility for players looking to build powerful X Antibody lineups. The card allows you to ignore its color requirements while controlling a Digimon, making it a seamless addition to your hand during critical moments. Its primary strength lies in its Main effect, which enables a specific Digimon without the X Antibody trait in its digivolution cards to digivolve into an X Antibody card from your hand with a reduced cost of one. When this digivolution occurs, the Proto Form becomes the bottom card of the new Digimon's evolution line, providing a strategic advantage in resource management.

Beyond its offensive utility, this card includes a Security effect that adds it directly to your hand when revealed, ensuring you never lose value from it. The Inherited effect provides a defensive layer, allowing you to return a Digimon card to your hand and place an X Antibody on top of your security stack when the equipped Digimon would leave the battle area. This dual nature of offense and defense makes the X Antibody Proto Form a valuable tool for collectors and players alike. The alternative art treatment adds visual appeal to this Special Rare variant, making it a standout piece for those seeking to complete their Promotion card collections. Whether you are building a competitive deck or simply appreciating the intricate mechanics of the Digimon Card Game, this card represents a key component of the X Antibody ecosystem introduced in the EX5 set.
