Spiritual Asylum

The whole point lives in the tension between its two clauses. Blanket shroud on your creatures and lands is an absurdly strong protective shell: no targeted removal, no land destruction aimed at your mana base, no Aura or pump from your opponent latching onto your board. The catch is the trigger that dismantles it the instant you swing. This is a defensive enchantment that punishes you for going on offense, which collapses it into a single, deliberate design lane: the lockdown deck that wins without attacking. Park it against an opponent who leans on targeted answers, win through enchantments, damage doublers, mill, or some other untargeted clock, and the asylum holds. The moment you decide combat is the path to the win, the protection evaporates by your own hand. That asymmetry (you control when it breaks, but breaking it is also the moment you most want to keep it) is what keeps the rate honest; a permanent shroud blanket with no downside would warp any board it touched. Note where the shell leaks: shroud guards individual permanents from being targeted, so edict effects that force you to sacrifice still slip through, because they target the player, not the creature. It also reads as a piece of an older protective grammar, before hexproof split the difference: shroud shuts off your own targeted effects too, so the asylum quietly turns off your combat tricks, your Auras, and any growth spell while it stands. A wall of glass that protects everything until you raise a fist.
