Well bad luck. In the manga, it is Wendy that uses more magic circles so the anime team would mostly do her, assuming they bother doing the circles anyway since Wendy just appears with them and that's it. The next would be with curses really but those aren't the magic circles you mean.

And again, like Nick mentioned, if they they take up valuable resources to make those circles, then best they don't bother. The new anime is currently not in my favour and that is WITHOUT magic circles to boot.
