Virgo Shaka was the first Virgo Saint in the game. Thanks to the Awakened Cloth, this control-type character had a brief moment in the meta a long time ago: for two energy, he could silence an enemy and start a chain of restrictions through Silence, Mute, and occasionally Hush. That made him valuable in slower matches where denying key skills could decide the fight, and Purifying Light helped him ramp Status HIT to improve consistency over multiple actions.
Today, however, his impact is too narrow and too expensive for modern team tempos. He still depends heavily on landing status effects, his pressure outside control is low, and he offers limited utility compared to newer controllers that provide broader disruption with better efficiency. Demon Pacifier also gives him a niche against summons, but that is not enough to justify him in most competitive drafts. In the current meta, there are simply many stronger and more flexible control options.
