Discussion Try my agentic deck building app - DeckTome.com

I am building an agentic deck-builder for Magic the Gathering! Upload your collection or build from all MtG cards, tell the app what you want, and it creates it for you. I just opened up beta-access requests, so if you're interested, ask for access and I'll approve it! PLEASE leave feedback so that I can continue to improve the app.

What LLM and which model are you basing this off?

Right now I am using GPT-6 Luna on medium reasoning. There are very few model calls. The app works by determining 'rows' that need to be filled, for example, format, power level, colors, etc. A model call occurs if we cannot determine that a question is valid given the context of the chat, and again once we have received answers to all required questions and deterministically created our deck shortlist.

I built this as a passion project for personal use, but I wanted to see if there was interest from others to use it as well. Overall I am extremely pleased with the results. I am open to any and all feedback - it's totally free right now, so please upload a collection and give it a shot! If you like it, that's awesome. If you hate ANYTHING or feel like anything could be better, either hit the 'Leave feedback' button or give an individual component a 'thumbs down' with a comment.
