Touch the Spirit Realm

The Oblivion Ring lineage of white removal enchantments always carried a structural liability: the answer is only as durable as the permanent holding it, so an opponent who breaks the enchantment gets the exiled threat back whole. This design keeps that familiar bargain (the enter trigger exiles an artifact or creature until the enchantment leaves) but bolts a second, unrelated mode onto the same card through channel. Pay one and a white and discard it from hand, and you exile a target until the beginning of the next end step: a blink for your own creature's enters-the-battlefield trigger, a save from a wrath, a blocker cleared mid-combat, or a reset that strips the +1/+1 counters and an opponent's Auras off a threat that returns clean under its owner's control. Because channel is an activated ability from hand rather than a spell that resolves, it dodges the counterspells and cast triggers that punish the enchantment half, and it happens at instant speed on your terms. The split resolves the old problem of removal enchantments sitting dead in hand against the wrong opponent. This card is never fully stranded: when the permanent-based exile is too slow or too fragile for the matchup, the channel line answers a question the front half cannot, and vice versa. Two effects sharing one card, each covering the situations that leave the other useless.
