I'm Not sure you will actually need those big Mana artifacts like
gilded lotus,
nyx lotus,
caged sun etc.. You don't have a Lot of high cmc or X-mana plays, so I would rather add more of These or remove some of those Mana Rocks. Alternatively, you could add some "
beast whisperer" effects so you can draw cards when playing your small creatures, effectively cantripping or even getting massive carddraw If you have multiple of those engines, which would make good use of the massive amount of mana some of your cards can generate. Hope this was helpfull for you, Checkout my latest Commander deck, I would love to hear your thoughts on it
