Brachydios

Trample, First Strike, Blastblight
Slimeblight - When this creature deals damage to a creature, add a Slime Counter to that creature, when that creature has 3 Slime Counters on it, destroy that creature (Slime Counters ignore Hexproof and Shroud).

Brachydios is easily identifiable by its glowing, green slime-covered horn and "fists," as well as its shiny, armoured hide covered in many plates and ridges.
