How to Build Your First One Piece TCG Deck (2026)

Deck building in One Piece TCG is about consistency, legality, and focus. Start with a clear plan, then refine it with testing. Haki TCG’s deck builder helps you move fast from idea → playable list. If turn timing or counter math is still unclear, read the 2026 rules guide first.

Step 1: Choose your Leader

Pick a Leader that matches your preferred playstyle. Leaders define your color identity, tempo, and win condition.

Step 2: Build a clean curve

A stable curve gives you plays every turn. Aim for a balanced spread of costs rather than stacking only high‑cost finishers.

Quick curve template

1. 10–14 low‑cost cards (1–2 cost)
2. 18–24 mid‑cost cards (3–5 cost)
3. 8–12 late‑game cards (6+ cost)

Step 3: Choose your staples

Look for cards that:

• Replace themselves (draw/filters)
• Protect your Leader
• Swing tempo in your favor

Step 4: Test and refine

Use Haki TCG’s Deck Builder to track edits and quickly swap cards after test games. Small changes make a huge difference in consistency.

Step 5: Check 2026 format legality

Bandai introduced Standard and Extra Regulations using block numbers from April 1, 2026. Before an official event, check the organizer’s named format, the current block-number pool, errata, and the banned/restricted list on Bandai’s official rules page. A valid 50-card color list can still be illegal for a specific tournament format.
