Spitting Slug

A combat puzzle dressed up as a creature, and a remarkably pure expression of an idea that mostly vanished from later design: first strike as a bargaining chip rather than a static keyword. The body, a 2/4, is built to survive rather than threaten, which is the point. The moment it blocks or becomes blocked, both players know first strike is on the table; the question is who gets it. Pay the green tax during that combat trigger and this creature strikes first, often killing an attacker or blocker outright before it deals damage. Decline, and first strike instead goes to whatever is fighting it, a real cost when that creature would otherwise trade evenly or die. The default-to-opponent clause is the elegant part: it turns inaction into a downside, so the mana you spend is buying out of a penalty as much as buying an advantage. That makes the effective combat math depend on board state, open mana, and what you can afford to lose, a lot of decision density loaded onto a single defensive body. The cleverness comes at the price of unreliability: if you are tapped out, the slug hands first strike to its assailant, and a defensive creature that punishes its own controller for being mana-light is a hard sell. It reads as an experiment in conditional combat abilities from an era when designers were still mapping how much friction a single creature could carry.
