Card Rulings:Gravekeeper's Supernaturalist

OCG Rulings

 * If "Gravekeeper's Esper" was Fusion Summoned, its ATK/DEF will increase by its own effect, but when the effect of "Skill Drain" is applied, it loses the ATK/DEF it gained. ("Gravekeeper's Esper" returns to having 2000 ATK/DEF.) Even if the effect of "Skill Drain" stops applying afterward, "Gravekeeper's Esper" does not regain that ATK/DEF.
