Aldrich, Devourer of Gods

Bestow {x}{b}{b}, Changeling.
X is target creatures converted mana cost.
If Aldrich, Devourer of Gods kills a creature, he
may either gain any keyword abilities that
creature had, or he may gain that creatures power
and/or toughness, or a +1/+1 counter.
When Aldrich ruminated on the fading of the fire, it
inspired visions of a coming age of the deep sea.
He knew the path would be arduous, but he had no
fear. He would devour the gods himself.
