Its a great card.
Pros:
-Great Poison. Easily ruins purify.
-Decent damage: Most of the shields in the game reduce damage by 1. This deals 2. Nuff said
-Speed: Its like a boulder going down a hill, once it gets moving, it wont stop easily.
Cons:
-Speed: Unless you take it out early, your not causing good damage with it.
-Damage: The weapon itself deals only 2/4 damage. Not the most powerful thing ever...
-Poison. You need Poison/Chyrosa in order for the poison to be truly helpful.
