Summary:
The Moonshot Collection is now available in MLB The Show 26 Diamond Dynasty, offering 99 OVR Craig Biggio and 99 OVR Mickey Mantle as collection rewards. Players need 23 eligible Moonshot Series cards for Biggio and 36 for Mickey Mantle. Since 40 cards currently qualify, you have four cards of flexibility. The best approach is to earn free rewards first, check your Binder, and then use MLB The Show 26 Stubs only for the cards you still need.
1. Understand the Moonshot Requirements
The collection has two important milestones. Collecting 23 Moonshot Series cards rewards 99 OVR Craig Biggio, while collecting 36 rewards 99 OVR Mickey Mantle.
There are 40 eligible cards, so you do not need to collect every Moonshot player. This four-card cushion can help you avoid expensive cards on the Community Marketplace.
2. Earn Free Moonshot Cards First
Start with the Moonshot Program before spending any Stubs. Complete its Moments, missions, PXP objectives, and other available tasks to earn Moonshot rewards through gameplay.
You should also check Moonshot Event content. Progressing through the Event reward path can provide additional eligible players while allowing you to make collection progress through normal gameplay.
3. Check Your Binder Before Buying
After claiming your free rewards, check your Diamond Dynasty Binder. Moonshot cards from packs, previous rewards, or other content may already be in your collection.
Every eligible card you already own reduces the number of cards you need to purchase. This can significantly lower the total cost of completing the collection.
4. Compare Marketplace Prices
The Community Marketplace is the most direct way to obtain specific Moonshot cards. However, prices can vary considerably between eligible players.
Make a list of the cards you still need and compare their current prices before purchasing. Because 36 of 40 cards are enough for Mickey Mantle, you can skip up to four expensive cards and use cheaper eligible alternatives instead.
5. Be Careful With Moonshot Packs
Moonshot Packs can provide eligible players, but their contents are not guaranteed to include the exact card you need.
If you only need one inexpensive player, purchasing that card directly from the Marketplace is more predictable. Packs can be more useful when you still need several cards and are comfortable with random results.
6. Unlock 99 OVR Mickey Mantle
Once you collect 36 eligible Moonshot Series cards, you can complete the requirement for 99 OVR Mickey Mantle.
Mantle offers considerable lineup flexibility, with eligibility across Center Field, First Base, Second Base, Third Base, Shortstop, Left Field, and Right Field. His switch-hitting ability also gives Diamond Dynasty players another flexible offensive option.
7. Best Collection Order
For the most efficient approach, follow this order:
Moonshot Program → Moonshot Event → Binder → Marketplace
Earn every available free card first, then purchase only the remaining cards required to reach 36. Use the four-card flexibility to avoid unnecessary expenses and monitor Marketplace prices before completing each purchase.
The main goal is not to collect every Moonshot card. It is to reach the 36-card requirement as efficiently as possible while keeping your MLB 26 Stubs for sale available for other Diamond Dynasty content.
