Onyx Talisman

Black spells were a designer's favorite trigger in this era, and this artifact watches every player's stack for them, offering an untap each time one is cast for an extra . The clause is broad: free a tapped blocker, reset a mana rock, ready a creature with an activated ability. But the toll prices each untap above what those effects usually justify on their own, and the engine only spins when black spells keep getting cast. Even when you control the spigot yourself, paying full freight for a black spell and then more just to untap a permanent is rarely a trade worth making. The cast-trigger rather than a resolution-trigger does soften one edge: it fires whether or not the spell sticks, so a countered or fizzled black spell still hands you the option. That hardly rescues the math. This belongs to the cohort of Ice Age low-rarity artifacts that landed nearer durdle than disruption: a card whose ceiling demands a board saturated with black and whose floor is an inert rock, with the untap rarely earning back both the install and the repeated payment.
