Cannot be Normal Summoned/Set. Must be Special Summoned (from your hand) by banishing 2 DARK monsters from your GY. 

Once per turn: You can target 1 monster your opponent controls; destroy it, then inflict damage to your opponent equal to half its original ATK. 

If this card destroys a monster by battle: You can Special Summon 1 Level 4 or lower Fiend monster from your GY in Defense Position. 

If this card would be destroyed by battle or card effect, you can banish 1 Fiend monster from your GY instead.
