Hibernation

Color hosers used to be blunt instruments: a single creature destroyed, a single spell countered, a few points of life drained. This one operates at the scale of a sweeper, but it bounces rather than destroys, which is the whole design tension. Against a green board it reads like a one-sided wrath, except every permanent the opponent loses comes back to their hand, so the tempo it buys is rented, not bought. The instant timing is where the card earns its keep: cast in response to a green deck committing its turn (a creature attacking, a fresh board of green threats already resolved) and the swing is enormous for the window it opens. It does not answer green so much as reset green's tempo to zero for a turn, which is a different and more interesting effect than killing things. The blanket "all green permanents" wording is what ages strangely; it scoops up green creatures, green enchantments, green artifacts, the rare green land like Dryad Arbor, the opponent's and your own alike. That indiscriminate breadth is the cost of the rate: it is devastating against a deck built on green permanents and dead air against everything else. Cyclical hate of this kind, mono-colored and merciless, is largely a fossil of an era when Wizards was comfortable printing cards that simply did not function outside one matchup.
