Terrakion got priority Close Combat? Cool.
Also Staraptor got priority Brave Bird with 120 Atk.
Resttalk Calm Mind Suicune with priority Scald.
Anyway, isn't adding new abilities make this a pet mod? Metagamiate just change the mechanics of the Normal moves. It doesn't modify something or add something new. This add some new abilities that isn't in the game, so basically this is a pet mod imo.
It's not adding a New Ability. It's making a canon out of an already existing Ability.
Hawluchange falls under the same category. It adds new moves, but simply modifies an already existing move.
