A comprehensive understanding of galaxy evolution requires a holistic view into the anatomy of galaxies and the baryonic processes that shape their growth.  Using a triad of properties—environment, mass, and time—I will present multi-wavelength studies of the extreme end of these parameters in distant cluster galaxies during the peak epoch of star formation.  Enabled by interferometric observations on the Atacama Large Millimeter Array (ALMA), I will focus on the first spatially-resolved images of molecular gas and star formation within high-redshift clusters, highlighting potential evidence for gas stripping and kinematic gas asymmetries. With ALMA, the regime of spatially-resolved gas kinematics and morphologies is burgeoning from case studies to a rich field of data, allowing us to push further back in cosmic time and opening up the potential for many new discoveries.
