Zero is right. Elza seems to be the middling ground between Piany and Chrome, with both offensive and supportive buffs. I also don't really see why you're comparing her to Lucius, as the only things they have in common are high hit counts and light mitigation.

Plus, as a spark buffer in this era, she is amazing. The past few spark buffers have had rather average hit counts, nothing close to what Elza's 6* has. Elza's 7* is one of the few combinations of Spark Buffer and Spark Blanket. And really? Avant replacing Elza as a sub? I think you severely misread either one or both of their skills if you think Avant can replace Elza. Rhoa's only advantage over Elza is an elemental buff, which isn't always useful. Her other buffs' clashes don't really matter either.

As for Uda, I again agree with Zero. In my opinion, Uda was much, much worse than Elza during the height of their time. Uda's drop buff was easily replaceable, while Elza's high hit count wasn't (I'm pretty sure Lario wasn't released yet), along with the strongest spark buff of the time. Though, by power creep, Uda might get an overall stronger Leader Skill, they definitely can't replace eachother since they have completely different roles. Rhoa is also outclassed, basically as soon as the next batch was released.

And here, have some squads for your challenge:

Elza-Piany leads    Korzan     Hadaron     Quaid     Shera

Piany-Krantz leads     Elza     Ciara     Shera     Griff

Avant-Elza leads     Shera     Piany     Aurelia     Griff

Elza-Elza leads     Elza     Elza     Elza     Elza (runs away with squads full of Rahgans and Hadarons)
