yeah i guess i was mainly asking about the red and white onesThe creature part of the gods don't need to be directly answered: you can kill the other permanents to lower devotion.
The non-creature effects of the gods are all things you can play around and don't really require removal EXCEPT for perhaps Purphuros who can just generate obscene amounts of damage in a dedicated deck in a way you can't really interact with.
Disclaimer: I haven't played with Heliod.
though if i run any of them i probably wont run the white one anyway
