Snorting Gahr

The whole design lives in the blocking step. Most green beaters of this size want to swing into open air and connect; this one wants to be answered, because the moment a blocker steps in front of it the 3/3 body swells to a 5/5 and the defender's math collapses. It punishes the obvious chump and trades up against creatures that looked safe declaring the block. What balances the design is that the bonus is reactive and temporary: it does nothing when unopposed, the controller never chooses to trigger it, and the +2/+2 evaporates at end of turn, so no permanent advantage gets banked. The result is a creature that reads as a 3/3 but fights as a 5/5 only on the turns the opponent allows it, handing the timing decision to the defending player and then taxing them for guessing wrong. It is an early articulation of the "bigger when blocked" template green would return to repeatedly, building a deterrence engine into the combat phase rather than the attack trigger.
