Regarding Ver. 4.0

The 4.0 update to the JP server brought about numerous changes to the game mechanics and drastically changed how song scores are calculated, and consequently the ways to form an optimal Scorer team. Listed below are additional variables affecting song score in Ver. 4.0, and whether their effects are been accounted for by this Team Builder:

☑ 10% bonus to cards whose idol belongs to selected song's idol unit

☐ Equipped School-Idol-Skills

☐ Center card's secondary leader skill

☐ Guest center's secondary leader skill

Ver. 4.0 Team Builder

There is an existing SIF Ver. 4.0 team builder written by 見習い師 (@minaraishi) available at:

Translations and Usage Guide by /u/euni_2319

I highly recommend JP server players to use this instead.

Usage Guide

  1. Enter your School Idol Tomodachi Username. (case sensitive)
  2. Click Fetch Accounts
  3. Choose the SIF account containing the cards you would like to use to build your team.
  4. Select a song to tailor your team to.
  5. Select the percentage of notes you are confident in getting PERFECTs.
  6. Select the type of team you wish to form.
  7. Click the BUILD TEAM button.
  8. Select the Team Builder tab above to view the team! (may take a few seconds to load)
Note: Currently cards with skill levels higher than 1 are still treated as cards with skill level 1.
Note: N cards are not included in calculations. If you think N cards are able to make the team, then the in-game Auto-Formation tool will be more than enough to help you form your teams.

Team Types

  • Scorer: Allows player to achieve the highest possible score based on song selection and % PERFECTs.
  • Perfect-Lock (Maximize Score): Team consists of account's best Perfect-Lock cards with the same attribute as the song. If there are insufficient cards to form a full team, the remaining slots are filled with cards that will maximise the score of the team.
  • Perfect-Lock (Maximize PLock): Team consists of account's best Perfect-Lock cards regardless of card attribute. Perfect for S-Comboing a song while disregarding song score.
  • Healer (Maximize Score): Team consists of account's best Healer cards with the same attribute as the song. If there are insufficient cards to form a full team, the remaining slots are filled with cards that will maximise the score of the team.
  • Healer (Maximize Healing): Team consists of account's best Healer cards regardless of card attribute. Recommended for tackling songs that you face difficulty completing.
