Menace
When Noxious Gearhulk enters, you may destroy another target creature. If a creature is destroyed this way, you gain life equal to its toughness.
If the target creature has indestructible, it isn't destroyed this way and you won't gain life. If it is destroyed but put into a zone other than a graveyard, you'll gain life.
