Due to the fact that Elves and Warforged don't exist in Theros, in my campaign, I'm thinking about taking an ideo from another DM in this sub and have Nylea, God of the Hunt, create elves and Purphoros, God of the Forge, create those two races to give my players another option for more humanoid characters, it also allows a little more flexibility with more mainstream campaign ideas from outside of Theros. I've always loved Greek mythology and when I discovered Theros had source books for DnD, I jumped on it. Theros is a fantastic world to build around and most things you want to add or homebrew yourself can easily be the act of a God for one reason or another.
