Destroy target artifact or enchantment.
Revolt — If a permanent left the battlefield under your control this turn, you gain 3 life.
"A key weakness in the design is its vulnerability to repeated, forceful blows."

If the target artifact or enchantment becomes an illegal target, Decommission doesn't resolve and none of its effects happen. You won't gain life.

Energy counters aren't permanents. Paying won't satisfy a revolt ability.

If Decommission destroys a permanent you control, it will enable its own revolt ability and you'll gain 3 life.

Revolt abilities check only whether a permanent you controlled left the battlefield this turn or not. They don't apply multiple times if more than one permanent you controlled left the battlefield. They don't check whether the permanent that left the battlefield is still in the zone it moved to.

Tokens that leave the battlefield will satisfy a revolt ability.
(09/02/2017)
Revolt abilities don't care why the permanent left the battlefield, who caused it to move, or where it moved to. They're equally satisfied by an artifact you sacrificed to pay a cost, a creature you controlled that was destroyed by Murder, or an enchantment you returned to your hand with Leave in the Dust.
