Arcanosaur

Arcanosaur is a common mage minion card, from the Rastakhan's Rumble set.

Strategy
Arcanosaur is a powerful board clear ability on a minion, comparable to Corrupted Seer or Duskbreaker in Wild. As an Elemental, it can be summoned early with Elemental Evocation for a surprise earlier board clear.

Frost Lich Jaina can often heal to full Health off of activating this effect.

Lore
It is unclear if this creature is the result of a becoming infused with large amounts of  energy in a manner similar to the elemental-infused dinosaurs of Un'Goro Crater, or if it is simply an arcane being that resembles a dinosaur. Whichever the case, Arcanosaur is unique to Hearthstone.
