Phantom Contract (幻契約; gen-keiyaku) is a family introduced in BS65, possessed exclusively by the Contract card, The Phantom Partner, Palm, and the Golden Cloud family cards with Contract Advent that support Palm.
Palm is regarded as a summoner in the lore who can summon pseudo Spirits from other dimensions and worlds to help in fight. Those pseudo Spirits are called "Vision", while written as "Phantom Souls (幻魂)". The name of Palm's Contract family is considered coming from that aspect.
Cards in the family are either Contract Advent forms of Palm himself, or Spirits that Palm got affiliated with on his journey traveling around Lecoulis together with Toa and the others.
