Keranos, Raging Tempest

Indestructible
Enchantments you control have haste.
The first enchantment you cast each turn enters
the battlefield as a creature with power and
toughness equal to its mana value in addition to
its other types and remains a creature as long as
you control Keranos. Then, Keranos, Raging
Tempest deals 3 damage divided as you choose
among any number of targets.
