## Description

The Digimon I Designed (BT21-100) is a distinctive Option card from the 2025 Digimon Card Game WORLD CONVERGENCE [BT-21] set. Printed with a C-rarity treatment, this card serves as a flexible engine piece for players building Guilmon and Growlmon-centric strategies. Its unique mechanics allow it to interact with the trash and enable cost-free digivolutions, making it a staple for collectors focused on specific character synergies within the Digimon Card Game. As a Purple Option card with a play cost of two, The Digimon I Designed offers multiple utility plays. While you control Takato Matsuki, you can ignore the card's color requirements, providing essential flexibility during gameplay. The main effect allows you to draw a card and trash one from your hand to place this card directly into the battle area. Additionally, a delayed effect triggers when your Digimon are deleted, offering further board presence. The card’s most powerful feature lies in its trash interaction. One of your Digimon bearing Guilmon, Growlmon, Gallantmon, or Megidramon in its name can digivolve into a card with those names residing in the trash without paying the cost. This ability significantly accelerates your game plan by bypassing memory costs for key evolutionary steps. For security checks, playing this card grants one memory and places it in the battle area, ensuring consistent value. Whether you are completing the BT21 set or optimizing your deck for specific matchups, this card provides reliable support. Its ability to recycle Digimon from the trash makes it a valuable asset for any player looking to maximize their Guilmon and Growlmon lineage. The card’s straightforward yet impactful rules text ensures it remains a relevant piece in the evolving meta of the Digimon Card Game.
