Zaglossus hacketti

{t}, Destroy target insect creature an opponent controls with converted mana cost of {2} or less.
At around 1 metre long, 0.6 metres tall and about 30 kg, Z. hacketti was the largest monotreme known to have existed. Z. hacketti had longer, straighter legs than any of the modern echidnas. Augee (2006) speculates that this feature made the animal more adept at traversing through thickly wooded forests.
