Marius Deuer grew up initially in Hanover, where he attended the Bemerode chess centre and joined a club at five. After his family moved to Aulendorf, he became a member of SC Weiße Dame Ulm. In 2020, aged twelve, he won bronze in Germany's under-16 championship. That year he also defeated a grandmaster for the first time, beating Petro Holubka in Kraków. His three IM norms came in Cattolica, Spilimbergo and Budapest, and FIDE awarded the title in 2023.

Deuer earned his first GM norm at Tegernsee in 2024. At the 2025 Mitropa Cup, he played first board for Germany, winning individual silver and securing another norm. He completed the final norm at the Ellobregat Open in December 2025. FIDE awarded him the grandmaster title in 2026. In club chess, he progressed from Biberach to Schönaich, making his Bundesliga debut in the 2022-23 season. He joined Münchener SC 1836 in 2025.
