Building your first One Piece Card Game deck? You've splurged on that powerhouse Leader and 50-card main deck, but what about the 10 white-backed Don!! cards? Do they really need sleeves? Can you play them "raw" or stash them in clear sleeves for storage?
Skipping sleeving your Don!! cards might save a buck, but it could cost you a Game Loss at tournaments. Bandai's official One Piece Card Game tournament rules require clear differentiation—and mishandling marked cards is a fast track to penalties. Here's your complete guide to One Piece TCG Don!! sleeves, rules, strategies, and protection.
1. Official Rules: Differentiate or Go Unsleeved (But Don't)
The most important reason to sleeve your Don!! deck is that the official Bandai Tournament Rules mandate differentiation.
The Rule: "Leader cards, as well as DON!! cards, must be sleeved in a way that differentiates those cards from the main deck, or do not have to be sleeved at all."
The "Raw Dog" Risk: While the rule says "do not have to be sleeved," playing with raw cards is a major risk. If a single Don!! card gets a scratch, a bent corner, or a marked edge, a judge could rule it as a "Marked Card." Even though Don!! cards are functionally identical, having marked cards in your game area is a penalty magnet.
Must-Have Differentiation
| Deck Type | Recommended Sleeves | Why? |
|---|---|---|
| Main Deck (50 cards) | Opaque colored (e.g., black, blue) | Identical, non-transparent backs prevent marking. |
| Don!! Deck (10 cards) | Different opaque color/design (e.g., red, green) | Visually distinct—no accidental shuffles or confusion. |
| Leader | Matches Don!! or unique | Same rule as Don!! for easy ID. |

2. Clear Sleeves for Don!! Cards: Casual Yes, Tournaments No
This is the most common question we get, especially since standard card sleeves are so affordable and look great.
-
For Casual / Locals: Yes. Since Don!! cards have a unique white card back (different from the blue map back of standard cards), clear sleeves make them easily distinguishable. Many local game stores are fine with this.
-
For Tournaments (Regionals/Treasure Cups): No. Judges at major events typically require Opaque (Solid Color) Sleeves for all decks to prevent any possibility of "Marked Cards" (where you could identify a card by a scratch on the back).
Our Recommendation: Use our standard sleeves for storing your Don!! collection in a binder, but for high-level tournament play, you will need to purchase a pack of opaque colored deck sleeves (which we don't currently carry, but are widely available) to satisfy the judges.
3. Bling Protection: Gold & Straw Hat Don!! Demand Double Sleeving
In the early days, Don!! cards were worth pennies. But today, players love to "max rarity" their decks.
-
Straw Hat Don!!: Features custom art of characters like Luffy or Nami.
-
Gold Don!!: High-value holographic promo cards that can cost $20-$50 each.
If you are using special Don!! cards, you must protect them. The table surface is dirty, and constantly sliding Don!! cards under your Characters (to give them +1000 Power) will scratch the delicate foil surface within a few games.
The Solution: Double Sleeving Even if you use a generic colored sleeve for the tournament, that single layer isn't enough to stop dust from scratching your foil. You need an Inner Sleeve.
The Perfect Setup:
-
Inner Layer: Precise Fit Inneer Sleeves (Put the card in upside down). This creates a vacuum seal that protects the raw card from dust and scratches.
-
Outer Layer: Your Opaque Tournament Sleeve (Put the inner-sleeved card in normally).
This "Double Sleeve" method ensures that even if you spill a drink or play on a rough table, your expensive Gold Don!! stays in Gem Mint condition inside its inner shell.
4. Storing Extra Don!! Cards: Bulk & Bling Separately
Most players end up with hundreds of basic Don!! cards. You don't need to sleeve all of them.
-
Basic Bulk: Store in a 3200ct storage box.
-
Special/Holo Don!!: Sleeve these in standard sleeves immediately and store them in your binder. Treat them like any other hit!

No. The rules strictly state your Don!! deck must be visually distinguishable from your main deck to prevent accidental shuffling.
