Yeah, I'm hoping Oranguru is bulky and has a reliable recovery move, Meloetta is good, but it's not that bulky to survive big hits, and I guess it's just not everyone's first choice of choosing either.
And yeah, Accelerock will be nice to have, and of course a pain for Fire, Flying, and Ice-types, plus with Lycanroc having Keen Eye, I'm hoping it allows it to see its opponent anyways regardless of Accuracy. Opponent cannot lower its Accuracy, and he's immune to opposing evasion boosts. Its just Keen Eye isn't on many useful Pokemon, and the ones who are useful that get it have another better ability to utilize. I think Keen Eye should boost Accuracy for the Pokemon with it, considering they should be able to see their target.
