"[LV1][LV2][LV3] (Your Attack Step) When your Spirits or Ultimates in the family ""Lord"" or ""Vassal"" attack, your opponent must exhaust one of their Spirits. If the Spirit exhausted by this effect has equal or less BP than the Spirit or Ultimate that attacked, send one core from the opponent's life to their reserve. [LV2][LV3] When there is Soul Core on your Spirits, all of your Ultimates gain the family ""Vassal""."
