Stir Up Trouble

One-mana kill is attractive only with a token or expendable artifact available; paying five is too slow, so this is fringe sacrifice-shell removal.

Could be wrong if Revealed token and sacrifice density may create a reliable shell, or Standard may offer cleaner black removal.

Fatal Push is already a widely played setup-free option. This can hit any creature but needs fodder or five mana, leaving niche sacrifice testing.

Could be wrong if A strong sacrifice deck could value the payment enough to make it a recurring removal spell.

Modern rewards one-mana interaction, but trading a permanent at sorcery speed is a major cost; artifact-sacrifice shells are the plausible test home.

Could be wrong if Cheap artifacts with meaningful sacrifice value could make the resource cost far lower than expected.

Legacy's cheap removal and tempo punish a sorcery that requires another permanent. It is only a speculative synergy option despite the B rate.

Could be wrong if A dedicated artifact shell could exploit the sacrifice as upside rather than a real card-cost.

Grixis Affinity is a credible artifact home; compared with Cast Down, this trades consistency for a potentially cheaper, synergy-positive kill spell.

Could be wrong if If its artifacts are too valuable to cash in, Cast Down and conventional removal will remain preferable.

Aristocrats and artifact-token lists can turn the extra cost into value, but narrow creature-only sorcery removal is not a broad optimized staple.

Could be wrong if High token and death-trigger density could make the sacrifice substantially more profitable than normal removal.

At worst this is five-mana sorcery removal; revealed tokens and Treasure make B plus expendable material realistic, yielding solid but not premium removal.

Could be wrong if Unknown draft speed and token availability determine whether it is usually efficient removal or clumsy five-mana filler.
