Additionally, from personal experience, Imprison Chandelure genuinely isn't enough to prevent trick room from going up. You may be able to stop it from going up immediately. However, your Chandelure won't be able to do much on the successive turns. I highly suggest running taunt on Whimsicott and instead of Zen Headbutt on Terrakion, strive for either stomping tantrum or protect. Max Quake + Steelspike boosts defenses which will be beneficial if you want longevity. Instead of Chandelure, I recommend Rotom-H or Incineroar. You will find things like Tailwind Metagross a huge pain, and you need counters for late game Glastrier or Metagross. If you are willing to give up Togekiss because of its less viability in this format, I would strongly advocate Landorus-T because of its great synergy with Rotom-H and provides Intimidates which can be crucial for switches. Another great thing about Landorus is that you can predict regieleki volt switches and prevent it from happening, allowing your ally mon to K.O Eleki.
These are just some recommendations from personally experiences, but if things have been going your way so far, by all means, continue the great effort.
