Yea, I don't understand how anything works in the MCU. Everyone is calling him "the god of stories" now but all we actually know is hes just regular Loki sitting in the "big chair" at the end of time and cannot leave. If he actually was the god of stories from the comics Wanda wouldn't stand a chance tho, he'd just trap her in a time loop like he did to the Beyonder and call it good.
