Galaxies migrate along cosmic web filaments from small groups to clusters, which makes the evolution of their properties look stronger as environments get denser. We introduce the MUSE gAlaxy Groups in COSMOS (MAGIC) survey built to study the impact of environment on galaxy evolution down to low stellar masses over the last eight Gyr. The MAGIC survey consists of 17 Multi-Unit Spectrocopic Exporer (MUSE) fields targeting 14 massive, known structures at intermediate redshift (0.3<z21.5. The spectroscopic redshift completeness is high: in the redshift range of [OII] emitters (0.25<z10^10^M_{sun}, the fraction of galaxies with M*<10^9^M{sun}_ decreasing significantly, even for star-forming galaxies. We also highlight peculiar features such as close groups, extended nebulae, and a gravitational arc. Our results suggest that galaxies are pre- processed in groups of increasing mass before entering rich groups and clusters. We publicly release two catalogs containing the properties of galaxies and groups, respectively.
