We propose to utilize a novel sample selection method, as well as extensive Chandra and HST archival images of distant clusters, to determine the evolution of normal galaxies and AGN in rich clusters of galaxies. Hydro-dynamical N-body simulations of ICM gas provide X-ray observables that match the ICM properties of over two dozen clusters at z=0.1--1.2 that are likely precursors to the present-day Coma cluster. X-ray and radio images find 6--8 AGN per cluster; optical/near-IR photometry provide photometric redshifts for red sequence and bluer starforming cluster galaxies for GMOS spectroscopy. Spectra will provide AGN and normal galaxy classifications, Lick indices for starforming properties, cluster membership and cluster dynamics. Outcomes include (but are not limited to) blue fraction morphology and evolution, AGN luminosity function evolution, X-ray/radio AGN properties, bulge-to-disk ratios for starforming systems, obscured AGN samples, galaxy populations in sub-clusters, and population gradients within clusters.
