Ravenous Smelter

When Ravenous Smelter enters the battlefield, you may have it destroy target artifact or enchantment. If you do, put
X Scorch counters on Ravenous Smelter, where X is the destroyed permanent's converted mana cost.
When Ravenous Smelter dies, it deals damage to target creature or player equal to the number of scorch counters on it.
