Pemmin's Aura

Four activated abilities welded onto one Aura, each repeatable as long as you keep feeding it: untap for blue, flying for blue, shroud for blue, and a stat nudge of +1/-1 or -1/+1 for a single generic mana that any color can pay. The untap line is the engine. Bolt it onto a creature that taps for mana or for damage and you have an arbitrarily large ramp engine or a repeatable ping, bounded only by your blue sources. The shroud line answers the standard knock on Auras: a creature you have sunk a card into is exactly what an opponent wants to remove, and you can grant shroud at instant speed in the same window they try, leaving the spell with no legal target. Flying converts a clogged board into a clock. The stat line reads as filler until you notice it runs on generic mana, off the blue you are already spending elsewhere: shrink the host into lethal range for a fight effect, or push it past a combat math threshold the defender was counting on. The whole design inverts an Aura's usual fragility, which gambles a card on a creature and prays nobody has an answer; this one buys its own insurance in the same window the threat materializes. Freed from the Real is the cheaper untap-only relative; the modal protection and stat manipulation make this the version you reach for when the host is doing something you cannot afford to lose.
