Should I pull Denia for my account?

I'm 10-15 pulls away from hard pity and have enough to get denia or lucilla without hurting my collab pull chances. I've been pretty casual and only tried unlocking endstate matrix this patch and could only get 16k on my first try and want to make more solid teams (i pulled carty and zani for waifu reasons only lmao)

It's either lucilla to boost my already strong hiyuki team, freeing lynae, or denia to help fill in a slot for amy.

If I get denia, how viable is an Aemeath, Changli, Denia quickswap team? I'm down to learn but not sure if it's worth the effort over a better playstyle.
