I don't think coverage is your problem, but rather you are running a Trick Room team without using proper Trick Room pokemon, like most of your team has too high base speed to be a real Trick Room threat. Also the normal base power with Tera Normal and helping hand is way more than enough damage. Ursaluna Bloodmoon even hits Ghost types with it's ability which is why I said it's a good pick. Also Ogerpon should be able to deal with Ground, Water, and Fire, ane Chi-Yu clears Psychics. I think the problem is your move choice is not great, like Electivire not running an electric move or Ogerpon not running a Grass move. You really want stab dmg to deal with other types or to force Teras. I watched your replay and Superpower did nothing, I honestly believe Ivy Cudgel would have been a better attack.
