Mystical Tether

—

3cmc enchantment that exiles a target artifact or creature until it leaves the battlefield, with an optional flash mode for {2} more. Functions as a white O-Ring effect hitting two permanent types; fits control and midrange as solid removal, and flicker shells can exploit the ETB by blinking the enchantment to reset and re-exile new targets. Rated tier-1 in Limited where tempo-positive exile is premium, but tier-2 in Commander and Brawl where more efficient or unconditional options exist (Generous Gift, Skullclamp, etc.).

• The flash upgrade costs {2} extra (making it a 5cmc instant-speed play), which is a steep premium; it's usually cast at sorcery speed for efficiency unless the situation demands ambush removal.

• In flicker/blink shells, bouncing or blinking this enchantment causes the exiled card to return, freeing the enchantment to re-enter and exile a new target — enabling repeated removal with a single card.

• Unlike cards like Banishing Light, this hits both artifacts AND creatures, which meaningfully broadens its utility in artifact-heavy metas like Commander.
