Sersei vs Selene vs Enchantress vs Morgan Le Fay

who wins

This would be a really interesting free-for-all, as they all have so much hax and one-off weirdness to throw around. Not really sure who take.

I'm leaning Morgan Le Fay, but there's a lot going on.

I'd say Morgan because on average magic beats matter manipulation (Sersi) and she's the most powerful mage here.

They are all capable of KOing each other just depends on who goes first. Sersi and Selene are VERY versatile. Morgan may have more overall power than anyone here but she needs to cast her spells for them to be effective (same with Enchantress). Selene and Sersi have ways to make sure you NEVER cast a spell if they want.

IMHO :
Sersi >= Selene > Enchantress > Morgan Le Fay

Sersi for me. Her tactical combat abilities are the reason.

Tough, not sure how it goes. Enchantress has the highest peaks but Sersi has crazy matter manipulation. If her eternal power isn't enough to overcome Enchantress' magic (Amora trans-morphed Thor, Loki, Dr. Strange, Wonder Man etc.), Amora wins.

Otherwise, Sersi wins, but often, magic > science based powers.

Selene is potentially really OP if she has enough souls.
