Rating & Analysis
Baseball Card grants x1.5 Mult per Uncommon Joker owned. At Rare $8, 3 Uncommons = x3.375, 5 = x7.59, 6 = x11.39 — among the strongest single-card xMult sources in Balatro.
The dream pairing is Uncommon mass-production. Stack scaling Uncommons: Hologram (+0.25 Mult per played card permanent), Fortune Teller (+0.5 per Tarot), Constellation (+0.5 per Planet), Ceremonial Dagger (eat left neighbor for +Mult), Ride the Bus (+1 Mult per No-Face streak).
Antimatter (+1 Joker slot) opens room for more Uncommons. Blueprint / Brainstorm itself is Rare (no count) but copies adjacent Uncommons. Tier lists rate S overall, SS in Uncommon-axis builds. $8 for x11+ Mult ceiling is theft.
Deck Ratings
| Deck | Rating | Notes |
|---|---|---|
| Anaglyph | S+ | Double Tag duplicates Uncommon Joker tags |
| Black | S | +1 slot — easier Uncommon mass-production |
| Plasma | S | Chip averaging amplifies xMult |
| Red / Blue | S | Stable on standard decks |
| Yellow | S | $8 trivial vs starting capital |

Tips & Usage
- Mandatory pickup. $8 for x11+ Mult ceiling is unbeatable.
- Prioritize Uncommon Jokers; reject most Common picks late game.
- Antimatter expands slots for more Uncommons.
- Anaglyph Deck doubles Uncommon Tag opportunities.
- Blueprint to its right with strong Uncommon = effective doubling.
Caveats
- Common / Rare / Legendary Jokers don't count — Uncommons only.
- Avoid Perishable — losing it collapses the build.
- Eternal locks the build path — but persistent value is fine.
- Uncommon production needs Antimatter / Negative Tag investment.
- Baseball Card itself (Rare) doesn't self-count.
