Raviel, Empereur des Phantasmes SOI-FR003

Neither Normally Summoned nor Normally Set. Only Specially Summoned (from your hand) by Sacrificing 3 Demon-Type monsters, and not otherwise Special Summoned. If your opponent Normally Summons one or more monsters, Special Summon 1 "Ghost Token" (Demon-Type/DARK/Level 1/ATK 1000/DEF 1000) for each Summoned monster, but it cannot declare an attack. Once per turn, you can Tribute 1 monster; until the end of this turn, this card gains ATK equal to the original ATK of the Tributed monster.
