Rune-Brand Juggler

Suspect was built as a downside mechanic (the menace is token upside; the can't-block clause is the real tax), and this design answers the obvious next question: if you have to hang a can't-block marker on your own creature, what should that creature be good for? The enter-the-battlefield trigger marks one body as bait, benched on defense but earmarked for something better. The activated ability then cashes exactly that permanent in: for five mana and the suspected creature itself, you get a -5/-5 that kills nearly anything. The drawback and the payoff live in the same permanent, so the ability only comes online once you have accepted that the suspected creature is going forward and not coming back. Note the constraint the ability enforces: it demands you sacrifice a suspected creature, not any body, and the Juggler only suspects one target on entry. Without an outside way to hand out suspect, the removal is a single shot, not a repeating engine; the second activation has to answer where the next suspected creature comes from. That is what keeps a two-drop capable of shrinking a five-toughness threat honest. It reads like a modest black-red aristocrats piece with a removal button bolted on, which is precisely the job: giving a self-suspecting creature something worthwhile to do with the body it has effectively benched.
