^in response to Jojo65, when you want to answer, a full rate is not a necessary requirement but you need to elaborate on your suggestions.
Your opinion is misinformed by the way - who are the Hyper Cutter and Mirror Armor users in Gen 8 UU? Absolutely no relevant Pokemon. Crawdaunt uses Adaptability for the STAB boost, and in the off chance you're facing a Kingler, Mawile or Pinsir, they're probably using Sheer Force or Moxie instead. Mirror Armor is the proper of Corviknight, an OU Pokemon. Intimidate, in fact, is the selling point of using Incineroar - his place in the metagame is that of a bulky pivot, which is also why you certainly don't want to invest Speed more than HP.
You should also know that Toxic is no longer a TM in Gen 8 so it is impossible to acquire in Gen 8 UU on Incineroar without hacking or using glitches - Toxic makes sense in a NatDex format, but the question has specified this is Gen 8 UU.
