Dauthi Jackal

Shadow was Tempest block's great evasion experiment: a keyword that walled creatures off into their own combat dimension, where only other shadow creatures could trade blows. Most of the cycle leaned into that as pure unblockable aggression, but the Jackal pairs the keyword with a removal clause. Its sacrifice ability, costing and the creature itself, destroys a creature that is blocking, which means it only does work during your own attack, when an opponent has committed a blocker to one of your attackers. Most of the time that blocker is another shadow creature, since shadow already means almost nothing else can stand in the way, but the ability does not require it: any creature blocking any of your attackers is a legal target. Spend the body, clear the wall, and remove that defender for good. It is a combat trick stapled to an attacker, designed for an environment where shadow-on-shadow combat was often the only combat that happened. That context is why the card reads as such a period piece: the ability presumes you have attackers being blocked, which in a dedicated shadow shell usually means the mirror, and shadow as a mechanic has barely resurfaced since. The Jackal is a clean record of how deeply Tempest committed to its parallel-combat idea, building a sacrifice-for-removal effect that assumes both players are fielding the same exotic keyword.
