Where To Get TM90 Substitute in Pokémon Black & White

Substitute TM on the ground in Twist Mountain (Pokémon Black)

TM90 Substitute can be found on the ground within Twist Mountain. You can access Twist Mountain from two areas, but it’s easiest to reach the TM by starting from the mountain’s exit in Icirrus City.

Also note that TM90 only appears in the Winter months, which correlate directly to real time months IRL.

Winter weather appears in Black & White during the months of April, August, and December.

Here are some key takeaways regarding TM90 Substitute:

  • The user creates the substitute using its own HP. The substitute takes 25% of the user’s HP for itself.
  • Substitute cannot be used if losing the required HP causes the user to faint. Pokémon Shedninja cannot use Substitute, as it only has 1 HP.
  • The substitute will take most damage inflicted against its user. The user will take damage from inflictions such as recoil or existing status conditions.
  • A Pokémon’s Substitute cannot be affected by new status conditions. It also cannot flinch or be trapped.
  • Several Status moves cannot affect a substitute. This includes Copycat, Lock-On, Mind Reader, Embargo, and Yawn.

Substitute is widely-used in competitive battling, as it can create turn advantages for the user.

Faster Pokémon really thrive with Substitute, since they can move first and avoid any predictable attacks. It can also allow you to safely learn more about your opponent’s move set.

The move is also frequently used against stalling opponents, or Pokémon who rely upon inflicting status conditions to slowly eat away at HP. By using Substitute, you’re able to avoid moves such as Toxic or Thunder Wave for at least one turn.

Substitute also works with Baton Pass as well.

Baton Pass allows you to give your substitute to another Pokémon in your party. This can help with predicting your opponent’s strategy depending on who they switch to, or can assist with setting up type disadvantages.
