PRE-EVENT CHECK · STANDARD
Check the deck before you travel.
Pick a major event, paste a 60-card list, and see whether the cards and language mix are allowed. If the data cannot prove it, you get UNKNOWN — not a guess.
- Event-specific language rules
- Current Standard marks: H / I / J
- Official links and last-verified time
Pre-check only. The head judge and official event page are the final authority.

HOW IT WORKS
Rules first. Unknown when unsure.
The checker uses the official 2026 Standard rotation (marks H, I, J), official event language policy, and current card data. It never presents a guess as a pass. Read the method.
