Infant Gorgon

Deathtouch
Whenever a spell or ability you control destroys another creature, you may mature Infant Gorgon.
(To mature this creature, exile it. If you do, search
your library for a non-Young creature card that shares a creature type with it. You may cast it by paying the difference in mana costs between it and this creature. Then shuffle your library.)
Scrutinizing death, their mode of maturation.
