Thopter Arrest

Banishing Light's exact duration template, narrowed at the target line. Where Oblivion Ring and Banishing Light reach any nonland permanent, this one stops at artifacts and creatures, and it asks the same for the privilege of doing less. There is no rate to point to as compensation: this is the same effect at the same price with a smaller field of legal targets, a deliberately constrained version pointed at the permanent types it was built to police. The exile-until-leaves clause is what does the work and what opens the seams. Routing the permanent to exile rather than the graveyard dodges indestructible, sidesteps regeneration, and denies any death-trigger or graveyard payoff its trigger. But the same clause hands the permanent back the instant the enchantment dies, so an opponent who can answer a three-mana enchantment recovers their threat, often at a moment they choose. The effect reads as a stay of execution rather than a clean answer, which is the tension every card in this family lives with: the temporary banish is strictly weaker than destruction the moment your removal is itself removable. What separates this design from its wider-targeting siblings is purely the narrowed scope, a card that trades reach for nothing and survives on being unambiguously good against the artifacts and creatures it was always aimed at.
