Pestilent Wolf

A green two-drop that turns its own attack into a threat of removal: for three mana per activation, the 2/2 body gains deathtouch and forces any blocker into a trade it will lose. The rate is the constraint here. Deathtouch on a small green creature is not scarce, but bundling it into a repeatable, mana-hungry activation on a vanilla stat line is a deliberate throttle. You pay the tax every combat you want the effect, so the wolf functions less as a beater and more as a per-turn tax on blockers: leave it unblocked or lose whatever stops it. Where a fixed deathtoucher like Typhoid Rats gives one guaranteed trade and then dies, this keeps offering the same threat as long as the mana holds, which matters more in a grinding board state than in a race. The activation is instant-speed too, so it can bluff: hold up the mana, and an opponent has to respect that any attacker or blocker might suddenly bite for keeps. That flexibility is the whole argument for the card, and it is a modest one. This is a common-rarity design meant to give green aggro a repeatable combat threat rather than a burst of power, filling the slot where a deck wants pressure that also punishes bigger blockers.
