What is the Rank UP System?
Increase the Rarity of SP Cards at Transcendence Lv9
The Rank UP system allows you to increase the rarity of Special cards that have reached Transcendence Lv9 by one rank. Increasing the rarity raises the training cap, so it's recommended to perform Rank UP without fail for players who have reached Transcendence Lv9.
Impact/Prime Cards are Eligible
Cards eligible for Rank UP are Impact and Prime cards. FA Impact and FA Prime cards are also eligible, so prioritize raising the Transcendence level of your main players.
How to Proceed with Rank UP
Raise the Rank UP Target Card to Transcendence Lv9
First, it is essential that the player you want to Rank UP has reached Transcendence Lv9. Raising the Transcendence level requires collecting many of the same player cards, so play diligently every day to acquire the necessary players.
Collect Cards of the Same Position/Rarity
To perform Rank UP, cards of the same position and rarity are needed as materials. For each rarity, prepare 3 material cards for the first Rank UP, and 5 for subsequent ones.
Collect Ultimate Coins
Ultimate Coins are one of the materials required for Rank UP. Ultimate Coins are mainly obtained by playing through League Mode, so it's important to play daily.
Required Number of Ultimate Coins
| Category | First Time | 2nd Time Onwards |
| Prime Rank UP |  ×4000 | ×8000 |
| Signature Rank UP | ×40,000 | ×80,000 |
| FA Prime Rank UP | ×3000 | ×6000 |
| FA Signature Rank UP | ×30000 | ×60,000 |
Transcend/Rank Up with Main Player Growth
Main Player Growth is a system where you can develop any Impact card into a Signature card using dedicated items. Normally, Rank UP and raising Transcendence levels require a vast amount of development materials, but with Main Player Growth, you can develop a card to Signature using only Main Player Coins.
| Tips! | Main Player Growth can only be performed on one player for each Transcendence level or Rank UP stage. |
Important Notes for Rank UP
Rank UP Has Monthly Limits
Rank UP has a limit on the number of times it can be performed for each rarity. After the initial Rank UP, there is a monthly limit, so carefully consider which players to Rank UP.
Rank UP Limits per Rarity
| Rarity | Limit Count |
| Prime Rank UP | 2 times/month |
| Signature Rank UP | 1 time/month |
| FA Prime Rank UP | 2 times/month |
| FA Signature Rank UP | 1 time/month |
Abilities Other Than Enhancement Level are 100% Carried Over
When Rank UP is performed, all development elements except for the enhancement level are 100% carried over. The enhancement level is carried over at 60%, so be careful.
How to Collect Ultimate Coins
Collecting Through League Mode is Most Efficient
Ultimate Coins can be obtained based on the results of the Postseason in League Mode. The higher the league, the more coins you can obtain, so try to play in the highest possible league.
