Aurorus gets Aurora Veil by breeding.
The legendary beasts get Extreme Speed.
Victini gets V-Create.
Previously these were event only.
Also looks like the Tapus are gonna be shit this gen. Tapu Fini didn't even get Life Dew.
Entei can run Extremespeed with any nature and ability it wants. It's still not that strong of a breaker, although it might prefer now to go for more mixed sets still with the priority like Arcanine (now with other natures other than Adamant).
A perhaps slightly relevant correction is that with the addition of the Hidden Ability Capsule, new movepools wil be unlocked that weren't available before.
One such wil be Vacuum Wave Blaziken being available with Speed Boost, which could potentially be relevant as it is priority and all.
You can refer to the PU Resources thread. There is a compendium for roles.
