Unstable Arcane Bomb

When you cast a noncreature spell or if this card
would be destroyed, sacrifice this artifact and lose
X life, where X is the number of counters on this artifact. At the beginning of your end step, the
next player on your left gains control of this
artifact.
Discard an instant or sorcery: Put a number of
Charge counters on this artifact equal to the converted mana cost of that spell.
Sacrifice another nontoken permanent: Put all counters from that card on to this artifact.
