What problem does it solve? Designing custom Yu-Gi-Oh cards without a reference baseline often produces cards that are too strong or too weak. This Skill benchmarks a custom card design against existing cards of similar function so its power level can be judged objectively. ## Core Features & Use Cases - Function-Based Matching: Identifies the card's primary function (negate, search, destroy, special summon, or draw) and finds 3 to 5 comparable existing cards via grep_search on CATEGORY flags or database queries. - Multi-Dimensional Comparison: Evaluates effect power, cost, restrictions, and stats (level, ATK/DEF, race, attribute) for each comparison card. - Balance Verdicts: Classifies the design as overpowered, underpowered, or balanced, with concrete adjustment suggestions such as adding cost or reducing restrictions. - Use Case: You designed a custom spell that searches any monster from the deck. Use this Skill to compare it against cards like Reinforcement of the Army and determine whether an archetype lock or once-per-turn clause is needed. ## Quick Start Compare my custom card design against existing Yu-Gi-Oh cards with a similar search effect and tell me if it is balanced.
