Enormous Baloth

Vanilla creatures exist to mark the curve, and seven mana for a 7/7 sits at the very top of green's: no evasion, no trample, no enters-the-battlefield value, just raw stats priced exactly where green's "big dumb beast" allotment lands. The number is the point. A 7/7 for seven is the rate green is permitted when nothing else rides along, the floor that fixes what every keyword and trigger above it is actually costing. That makes it a reference object more than a card anyone builds toward: it tells you what a Beast with trample, or one that loots on arrival, is paying for the privilege. The flavor handles the rest, a baloth being the genericized green megafauna of the period, the thing a set reaches for when it needs a large creature with no story attached. It is the green endpoint of the rate ladder, the version that closes games on stats alone and asks full price for the courtesy.
