Any suggestions to make this TR team stronger? (Champions Doubles)

I love Trick Room, and I used this team to climb to Master Ball in M-A. However, this team hasn't been feeling great, and can crumble in front of some new threats like Staraptor and Ychu.

I'm fine if things switch around a little bit, and like a secondary strat is added (I \*adore\* Sunroom, but it's missing some pieces like Liligant that I need)

Some things I've considered are a Mega-Zam + Meowstic package to pivot hard for Expanding Force PsySpam (which I may build regardless), a Mega Mawile secondary mega (which competes with Kingambit, but king doesnt take a megs slot)

Any suggestions y'all? I know it's not the strongest around but I'd love to improve.
