Honestly can't agree. Kruphix even acknowledged the Theros gods weren't omnipotent, and even a random mortal could ascend once he figured out they weren't. In most mythology as well it isn't Gods >>>>>>>>>> the rest. You can have perfectly mortal beings doing amazing things, or half deities taking on Titans. Gods fall from their spot, and mortals can rise up to that same level as well. Honestly if they made Theros deities so amazing nothing could stop them but other Theros deities that wouldn't be at all accurate to Greek mythology.
