Cave Tiger

A small lesson in combat psychology rendered as a triggered ability. The 2/2 body punishes the defender for the act of blocking, swelling the moment a creature stands in its way. That clause inverts the usual math of the attack step: answer this 2/2 with another 2/2 and the expected clean trade collapses into a one-sided loss, so the rational defensive play is often to take two and wave it through. The card turns the opponent's decision into the threat, which is a different posture from a pump spell you fire off yourself. The trigger keys on being blocked, so it stays inert on defense and inert when the creature connects unopposed; the bonus exists purely to make combat ugly for the player on the back foot. Read the trigger closely. It fires whenever the creature becomes blocked by a creature, so a multi-block stacks the bonus, one +1/+1 per blocker, and committing two bodies to gang it down can grow it right past the math the defender counted on. Because the boost expires at end of turn rather than sticking as a counter, the threat resets each combat instead of snowballing, which keeps it modest. It is a clean, self-contained take on the "punish the blocker" template green has returned to many times across its history, the kind of efficient common that quietly teaches a newer player how the attack step actually works.
