What I want Mega Delphox to have as an ability if it's in the game

Oracle: Moves that take more than one turn to activate instead activate immediately when they are used.

I really like this concept for Delphox who is based on the Oracles of Delphi, that give premonitions of the future to those who consult with them. Delphox knows the future and can land those attacks instantly.

The only current moves that can use make use of this ability are Future Sight, Solar Beam and Wish.

Having a 1 turn future sight with 120 base power, one turn solar beam, and some stat allocations to speed and special attack would make Delphox a massive threat with great coverage in Fire/Psychic/Grass. You could run a sweeper set with nasty plot, or a Fire Move/Future Sight/Calm Mind/Wish set for longevity.
