Non-Standard League Deck Checker

What is this?

This is a convenience utility to check a decklist against the legal cards for a given season. It's custom-built for the League, so it might be a little buggy. No data is collected or logged, so your deckbuilding secrets are safe with the checker. Please report any issues to Andy#3576 on Discord, and they will fix them.

How do I use it?

• Ensure that the right season is selected (defaults to current season).
• Paste your decklist in the mainboard and (optionally) sideboard text boxes. The TXT export from most deckbuilding programs should work:
• One line per unique card formatted "[number of copies] [card name]"
• e.g. "4 Oko, Thief of Crowns"
• Click the "Check" button to see a list of feedback about your deck's legality.
