1. Speed Stat:
* The Pokemon with the higher Speed stat will generally attack first.
* You can check a Pokemon's Speed stat in its summary screen.
2. Priority Moves:
* Some moves have priority, meaning they act before other moves, even if the Pokemon is slower.
* Priority is measured in stages, with higher stages acting before lower stages.
* Moves with a higher priority will always act before moves with a lower priority.
Examples of Priority Moves:
* Quick Attack: +1 priority
* Fake Out: +1 priority
* Extreme Speed: +1 priority
* First Impression: +1 priority (only on the first turn)
* Sucker Punch: +1 priority (only if the opponent is about to use a physical attack)
* Protect: +4 priority (can only be used once per turn)
* Detect: +4 priority (can only be used once per turn)
3. Other Factors:
* "First Turn" Priority: Some moves, like First Impression, gain additional priority on the first turn of the battle.
* "Quick Claw" Item: This item grants +1 priority to one random move each turn.
* "Prankster" Ability: This ability gives +1 priority to status moves.
* "Gale Wings" Ability: This ability gives +1 priority to Flying-type moves in the first turn of the battle.
How to Determine Order:
1. Check Speed Stats: The Pokemon with the highest Speed stat generally goes first.
2. Consider Priority Moves: If both Pokemon have priority moves, the move with the higher priority will act first.
3. Look for Special Conditions: Consider factors like "First Turn" priority, Quick Claw, Prankster, or Gale Wings.
Remember: The Pokemon with the higher Speed stat will only act first if neither Pokemon has a priority move.
