Portable Hole

White's cheapest reactive answers each ask for a concession: Path to Exile ramps the opponent, Swords to Plowshares gifts life, Condemn needs an attacker to work at all. This one trades those costs for a different exposure. The exiled permanent snaps back the instant the artifact leaves play, so the answer persists only while the artifact survives; any Disenchant effect cuts the tether and returns the permanent intact. That temporary nature is what buys the rate: not deck-thinning, gone-forever exile, but a lockup that artifact removal can unwind. The two-or-less restriction draws the other line, carving out a specific slice of the board (mana dorks, aggressive early drops, small planeswalkers when they qualify, problem tokens) while leaving anything heavier untouched. The design sits so cleanly because white gets a permanent-based answer that catches creatures and noncreatures alike, occupying the same structural niche as Oblivion Ring at a third of the cost, but deliberately scoped down so it can never sweep up big threats. This is the baseline of white interaction, distilled: fast, broad within its narrow band, and honest about how much white should be allowed to erase this early.
