Stegosaurus

Stegosaurus is a Jurassic herbivore that is far more dangerous than it appears. It opens each turn with a spin attack and actively seeks out grass tiles to graze, healing 5 HP from tall grass or 2 HP from short grass. It counterattacks any unit that strikes it from behind, making flanking unusually risky. Its Trample ability damages units it moves through. Removing grass tiles from the arena starves it of healing and denies a key part of its sustain.
