I wonder how her commandement would trigger. Just like I wondered the same for Monspiet, Glox and Balor.
Anyway, the plot seems to go for a Mael vs. Meliodas match at some point, so I don't think thet'll get rid of his commandements.
But perhaps since Ban will bring back Mel's emotions, there's no need for Mael to collect graces or decrees.
Anyway, I wish we would see Merlin Escanor Ludociel vs. Zeldris Chandler Cusack. I'm sick of those crappy moral dilemma that are just here to cover the plot weaknesses (Tarmiel releasing Mael, like really ? What are you even on about bro ?) and seeing Elisabeth doing nothing but complaining about stuff and being a burden.
I swear Gowther has been making the same face since the Holy War started. As much as I want Elizabeth to do something, Im more concerned that Gowther hasn't just Jacked or Blackout Arrowed Mael. He has so many abilities,but just like against Chandler he just sits around on Hawk doing....nothing
