Indomitable Archangel
Most protective effects guard one permanent at a time: a hexproof aura on a single creature, a regeneration shield, a fog for one combat. The static ability here works at the scale of a whole board, blanketing every artifact you control in shroud the moment your count reaches three. For an artifact-heavy deck, that is not a safety net but a wall against the specific category of disruption that has to pick a target: spot removal, artifact destruction, and your opponent's combat tricks all lose their handles at once. Shroud is narrower than it looks, though, and the design depends on that narrowness. It stops targeting, not the player-facing or untargeted lines, so edicts and sacrifice effects that hit the player still get through. It also cuts both ways: your own equip steps, targeted buffs, and Auras on those artifacts go dark the instant the lock comes online, so the protection is a state you flip for the board rather than a tool you can aim. The deeper fragility is that the Angel is the source of the effect, not a beneficiary of it. She is a creature, so the shroud never covers her, and any answer to her switches the lock off for everything underneath. That is the whole tension: you overcommit to artifacts to earn the blanket, then guard the one card that is itself the only thing your opponent needs to remove.
