Seven mana for a 7/7 trampler is a rate that stopped competing at the top of the curve a long time ago, which leaves the extra-blocking clause carrying this Treefolk. Most fat green beaters are sold purely on offense; this one is built to do double duty, soaking two attackers in a single combat without dying to either, then swinging back for seven through whatever's left. It is a wall and a finisher in the same body, the kind of card a defensive green deck runs when it wants one slot to both stabilize the ground and threaten to close. Trample earns its keep more on a creature this size than it usually does: at 7/7 it turns chump-blocks into a punishment rather than a delay, which means an opponent who commits two bodies to stop it is also exactly the opponent it was best positioned to block in the first place. The design tension is honest. You pay a steep price and get no card advantage, no protection, and no repeatable value engine; what you get back is a creature that reshapes how an opposing board has to attack and block around it. That is a narrow but real niche, and it explains why a card with no flashy text keeps surfacing in green decks built around outlasting the opponent rather than outrunning them.
