I'm not getting into the weeds here, but I would totally play a Sun-Soul Monk that has been blessed by Apollo and Hermes.
So, still winding my way through Theros, and reading up on Piety. It's a fascinating system, but I do feel it needs some fine-tuning. I like the Gods having "Do X to gain piety, Y to lose it", and I like that they aren't all the same. But it is notable that some gods are way easier to gain piety with than others. I'd probably try and find some minor and major ways to gain piety, performing major deeds nets more piety. Or just give each one a point range, or a die roll. Like a minor act that gains piety gains 1d4, while a major act gains 1d10. Still grokking the system, but it is interesting.
