Justice League Dark

In a flashback, exorcist and con man John Constantine and Jason Blood engage the Demons Three in a poker game for high-end stakes; Constantine offers his home, the House of Mystery, as his part of the pool in exchange for a box of artifacts, including a chipped Dreamstone. When both parties are caught cheating, Constantine has Blood summon Etrigan — a demon forced to share a body with Blood — to dispatch the demons. Afterward, Blood reprimands Constantine for making him summon Etrigan, and the two part ways.
