The morituri is an interesting choice to mix with Euryale. I have limited experience with morituri, but they seem like the ludus that "doesn't play nice with others", since half of their gig is triggering those skull effects, of which Euryale has none, so that's two stages of not having a
. But, one of the things I like about this game is that I'm always surprised to see how certain combos mix and how being unconventional can end up working well. I'm looking forward to seeing how she works out, from the perspective of someone who keeps his ludii pure, with the exception of a Wendigo that's coming my way.
I can see Euryale adding some nice heavy hitting and map pressure, and thematically, she does fit with morituri the best.
As for your question about different ludii taking gorgons, it depends on the gorgon. The three are very different from each other in terms of the role and function they serve as part of a team. One of my buddies has claimed, and I agree, that Medusa would work quite well for the legio. When she gets in nice and close, she can use ichor to heal, stacking with the heal from Gaius Pallidus, giving you a ghastly regeneration comp. Personally, for Euryale, I think she would work great with Legio XIII as well. With her being a titan, she can move through units and get behind your enemy, then trap them between her and your other Legio gladiators, triggering coordinated strike and keeping them in range of her constrict.
I'm sure there are other combinations that work well, and probably better, but that's what comes to mind.
