Executive Summary

The Mekk-Knight archetype offers a unique, reactive playstyle centered on column-based gameplay. As key figures in the "World Legacy" lore, they manifest on the field by capitalizing on the opponent's board presence, making them a premier "go-second" strategy designed to break established fields. Their strength lies in turning the game board itself into a puzzle, forcing opponents to reconsider every card placement lest they create the very columns of light from which these powerful knights emerge to generate overwhelming advantage.
