Jaxis, the Troublemaker

The activated ability turns a discarded card into a temporary copy of another creature you control, and the fine print carries the whole design: the token gets haste, a death-draw rider, and a mandatory sacrifice at the next end step. That sacrifice is the tax on the effect. You are not building a permanent army; you are renting one enter-the-battlefield trigger and one attack, then cashing the body in for a card. Point it at a creature whose ETB does the work (a Titan, a plunder-on-arrival body, a value engine) and the sacrifice stops mattering, because the trigger has already fired and the token replaces itself when it dies. The "another target" wording matters: she cannot clone herself, so she stays the engine that duplicates the payoffs rather than a self-replicating threat. The sorcery-speed restriction and the tap keep it to one activation per turn cycle, so it reads as a repeatable, discard-fueled clone engine rather than a burst combo. Blitz on the front half rhymes with the ability it grants: cast her for the cheaper cost and she becomes exactly the kind of hasty, self-sacrificing, card-drawing token she would otherwise make, a swing-and-replace threat that dodges sorcery-speed removal by simply not sticking around. Two abilities describing the same disposable-creature template from opposite directions, one for the commander herself and one for whatever she chooses to duplicate.
