A three-mana sorcery-speed Aura is far less efficient than Modern interaction; unlike Dress Down, it permanently locks one creature but is vulnerable to removal.

Could be wrong if A prominent hard-to-answer creature threat could make permanent tapping and ability loss a worthwhile niche answer.

Legacy's efficiency makes a three-mana targeted Aura a poor answer. Dress Down is cheaper, instant-speed, and already only a situational tool.

Could be wrong if A specific creature or counter-based permanent could create a narrow sideboard need for a lasting lock.

A complete creature lock is stronger than Lignify's body change, but the extra mana, blue cost, and Aura vulnerability limit it to a possible control option.

Could be wrong if Pauper's available cheap removal may leave no reason for blue decks to accept a three-mana Aura.

It can suppress a problematic commander or counter-based creature, but one removable, sorcery-speed lock is narrower than flexible answers like Touch the Spirit Realm.

Could be wrong if Commander-centric tables may value the counter removal and no-untap clause more than expected.

This is reliable common creature removal: it immediately taps and then blanks a creature indefinitely, with counter removal as useful upside. Aura risk keeps it below bomb status.

Could be wrong if Unknown format speed, enchantment removal, and archetypes could make Aura-based removal materially worse or better.
