Cleric/moon Druid gish builds in 5e - eviltoast

I was thinking about crazy optimizations today and I’m surprised we don’t hear more people talk about this combo. A cleric that can cast lvl 3 spells can concentrate on spirit guardians and wild shape, and by becoming a large creature you can create a 40 ft field of fast moving justice taking the dodge action - that include spider forms, which allows ceiling walking to create the disco ball of death moving around a room out of melee reach.

I’m surprised I’ve never seen this build being abused.
