Sinnoh team and progression basics
A starter guide to Pokémon Platinum: choose your starter, check the move category, prepare for the league, plan your postgame.
Original Nintendo DS release; not Brilliant Diamond or Shining Pearl.
Choose your starter
Turtwig, Chimchar and Piplup begin different team paths. Choose the one you enjoy, then add partners that cover its weaknesses rather than filling your party with similar types.
Check the move category
Platinum separates physical and special attacks by move, not just by type. Compare a move’s category with your Pokémon’s Attack and Special Attack before deciding which move to replace.
Prepare for the League
Carry healing items and status cures, and train several party members rather than relying on one attacker. Before a difficult battle, check your team for shared weaknesses and unused held-item slots.
Plan your postgame
The Battle Frontier offers a different challenge from the story. Treat competitive team building as a separate goal after the League; a story team does not need perfect breeding to finish the campaign.
Give each teammate a useful job
A second attacker, a status move and a dependable way to recover matter more than filling the party with six similar damage dealers. Check move categories when a new move is offered, and compare them with the user’s stats. Keep field-move access in mind as badges open routes. The early team can change as the regional roster expands, so a temporary partner need not become an unwanted permanent commitment.
Follow Platinum’s changed Sinnoh
Use Platinum’s Gym order and encounter tables, especially around the earlier Hearthome challenge and the expanded regional Pokédex. Record blocked routes with the needed field move, then return after gaining access. Before a long Galactic or League sequence, heal and review held items. The story’s Distortion World route is specific to this edition, so Diamond and Pearl instructions can disagree even when the town name is familiar.
