Using MLB to increase Support Card Level in Umamusume: Pretty Derby explained

To put it simply, MLB is the key to maxing out a Support Card’s capabilities. Support Cards play a huge role in training your horse girls efficiently, and Max Limit Breaking helps by pushing these cards beyond their standard limits.

How to Max Limit Break Support Cards

The process of MLB in Umamusume: Pretty Derby involves a bit of grinding and luck, especially if you’re a Free-to-Play player. The system requires you to obtain multiple copies of the same Support Card to “uncap” it. You’ll need to uncap a card four times to fully Max Limit Break it, and that’s where the challenge begins.

Here’s how to go about it:

• Head to the Enhance section from the main menu.
• Select Support Cards, then tap on Uncap.
• If a card is eligible for an uncap, you’ll see a pink horseshoe icon on it.
• Use duplicate cards to uncap it — no in-game resources are consumed in the process.
• Repeat the process four times to achieve MLB.

While this is doable for R and SR cards, SSR cards are much harder to Max Limit Break. Their pull rate is typically under 1%, and getting four duplicates is either a test of extreme luck or a sign your wallet has taken a hit. That’s why many players focus on Max Limit Breaking lower rarity cards first.

If you ever find yourself with extra duplicate cards after completing the Max Limit Break process, don’t worry, you can convert them into Cleats, which are used for other in-game enhancements.
