[Scripting Question] Help with Custom Moves and Abilities

[Mutant Yoshi]

So I've been working on a few custom abilities and custom moves recently, and I've came up with a few ideas of what I want. However, I'm not sure how to go about coding them. I was wondering if anyone could help me with these:

Abilities

Spoiler:

Induction - Any stat increased by the user, its partner gains as well

Cursed Glare - Prevents the opponent's side from increasing their stats.

Drive Off - Physical attacks from the user have a chance to make the opponent switch out (or flee if it's a wild battle)

Moves

Spoiler:

Sonic Wing
Flying
65 base power
Physical
Ignores type resistances

Healing Scale
Dragon
