>>34246293The only things that Day outruns that Dusk doesn't are Espeon, Froslass, Jumpluff, Dodrio and A-Dugtrio. There are obviously more, like Gengar, but they are OU and irrelevant to this discussion because Lycanroc won't rise above RU.
Out of those threats, Dugtrio is non-existent and the rest of them lose to Accelrock because they themselves do not have their own priority. The exception is Espeon.
So basically, the ONLY REASON to use Day Lycanroc over Dusk is if you are irrationally afraid of Espeon
