Baazkaban, Spreader of Malice

Indestructible
Baazkaban isn't a creature unless it has thirty
despair counters on it. Whenever an enchantment,
a land, or a creature enters or leaves the battlefield, put a despair counter on Baazkaban. Nontoken enchantments you control are X/X enchantment creatures, where X is equal to their converted mana cost.
