Search openCaselist cards by argument

openCaselist is where debaters disclose their cases. Card it searches the evidence cards in those disclosed files by argument, so you can find the card you need without knowing which team cut it.

How it works

Start from the argument. Decide what you need: a link, an impact, a piece of defense, or a specific author.
Search in plain language. Describe the argument in Card it, or search an author’s name, and pick the event and season you want.
Read the tag and cite. Every result shows the card’s tag and citation, so you can tell quickly whether it says what the tag claims.
Check the source. Open the original article or study and read the card in context before you read it in a round.
Look at who read it. To see a team’s full disclosure, browse their page on openCaselist, or use Scout it to search cases by Aff or Neg.

What openCaselist is

openCaselist is the site where debaters disclose their arguments. On the national circuit it is common for teams to post their cases to the wiki after a round, which is why it holds so many finished cards.

The wiki is organized by event and season, then by school and team. That layout works well when you already know whose files you want to read.

openCaselist and Card it

Browsing the wiki starts from the team. Card it starts from the argument: it searches the cards inside disclosed files, so you can compare how different authors support the same claim, then follow a card back to the source.

Card it is independent and is not affiliated with openCaselist.

How to search openCaselist by hand

On the wiki itself, pick the event and season, open a school, then a team, and read their disclosed rounds and files. To find a specific argument this way you open each team’s files and search inside them, which is slow when you do not know who reads it.

Tips for searching cards by argument

Search a full claim, such as “moratorium shifts data centers abroad,” rather than one keyword.
Search an author’s last name when you know the card but not the team.
Filter to your event and season first, then widen to the multi-year archive.
Compare several cards on the same claim and pick the most qualified, most recent author.
Open the source file to see how the team used the card in context.

What Card it covers

A multi-year archive of Public Forum, Lincoln-Douglas and policy evidence, 2013 to 2024.
Current debate seasons, including the 2026-27 Public Forum, Lincoln-Douglas and policy sets.
A free tier that searches past seasons since 2013; Card it Premium and Debate it All unlock the full library.

Using disclosed evidence responsibly

A card you find is a starting point. Read the full source, check that the tag matches the evidence, and follow your league’s evidence and disclosure rules.
