What? HELL NO! The only SSR that could eventually replace Raph is Eros. Metatron is trash tier and the only valuable reason to give Michael a regular spot is for a Shingen build.
Which he should since PFB is the meta, without PFB you will never have competitive dmg, raphy is for stalling, if you need raphy for stalling that means your team and grid were never good to begin with.
