Wyluli Wolf

A combat-math puzzle printed as a two-mana creature. The tap-activated, single-target pump predates the era when green's pump effects mostly migrated onto instants (Giant Growth and its descendants) or onto static team buffs; what Wyluli Wolf offers instead is a repeatable buff stapled to a body, paid for once at the time you cast it and reusable every turn thereafter. Run the math across a game and the rate looks absurd: a free +1/+1 every turn for the rest of the game. The two checks that hold it down are both built into the body. The 1/1 frame dies to almost anything, so the engine is fragile, and the tap cost competes directly with the Wolf's own attack, forcing the pilot to choose between swinging with it and pumping something else. That tension is the whole design: every turn you decide which single attacker most needs the point, rather than buffing the board for free. It became a small template for green creatures that tap to pump one target, and it remains the cleanest surviving example of a design axis green largely set aside once distributed pumps gave way to anthem-style board buffs (Glorious Anthem and the like). The interesting decision lives in the targeting, not in the activation: the ability is always available, but each turn it points at exactly one creature, and choosing which one is where the game gets played.
