Sapphire AI theory

Example: Roxanne's Nosepass on its first turn, with 39/39 HP Mudkip

Code checks in order:
1. Kill range
2. Rock Tomb speed drop effect
3. Harden (setup move)
4. Damaging moves

1. Kill range
- Is Mudkip in kill range? Since no, skip this step

2. Rock Tomb speed drop effect
- Is Mudkip faster than Nosepass? Since yes, roll a number between 1 and 100
	> If number is 1-70, +2 to Rock Tomb
	> If number is 71-100, +0 to Rock Tomb

3. Harden (setup move)
- Is this Nosepass' first turn? Since yes, roll a number between 1 and 100
	> If number is 1-80, +2 to Harden
	> If number is 81-100, +0 to Harden

4. Most damaging move
- Use the damage formula to calculate rolls for each move (example: Rock Tomb 13, Rock Throw 14, Tackle 6)
	> Give +2 to the move(s) that do the most damage

Use the move with the highest priority (for example, if check #2 rolls 50, check #3 rolls 50, and check #4 rolls 14/14/6 dmg, Rock Tomb would always be used because it has +4, Harden has +2, Rock Throw has +2 and Tackle has 0)

MANUAL TEST (save states):
Harden			19/50
Rock Tomb		28/50
Rock Throw		3/50
