Hi everyone,

NemeDraft is a free and open source draft overlay for MTG Arena. It's staying free. No ads, no telemetry, you retain all your data. I made it after reading a lot of research papers about MTG draft theory and I was surprised no similar tool existed for free (please correct me if I am wrong).

Behind it isn't ChatGPT, Claude, or Gemini looking at your pack and hallucinating. It's a specialized transformer I trained from scratch on Arena draft data: roughly 6 million platinum-or-higher picks for pre-training, then fine-tuned on around 400k picks from trophy decks only. It does one thing: rank the cards in your pack given your current pool and the archetypes still open.

The model isn't optimizing for average winrate. It's trying to pick what a trophy drafter would pick in your exact situation. Sometimes that's the card with the best raw stats/WR. Sometimes it's a worse card on paper that locks you into a coherent archetype. There is also a column in the UI showing the GIHWR from 17Lands. At the end of the draft, the overlay also hands you a 40-card decklist built from your pool.

Accuracy on SOS (Secrets of Strixhaven set):

- Top-1: 64.9% -> on ~2 out of 3 picks, the card the model ranked #1 was exactly the one the trophy drafter took.
- Top-3: 94.5% -> on ~19 out of 20 picks, the trophy pick was somewhere in the model's top three.

That second number is the one I actually care about, because it means the right pick is almost never hiding outside the top of the list.

The overlay is done and running in closed beta. I need more eyes on it before a wider release.

I'm specifically after:
- Gold or Platinum rank and above (Premier or Quick Draft)
- People who draft often, not once a month
- Testers who will actually report bugs and talk to me, not install it, draft one time, and vanish

If that sounds like you, DM me and I'll send a Discord invite.

The project: https://github.com/negaga53/nemedraft-client (open source)

Here is a demo of a EOE draft I did recently using the overlay: https://youtu.be/O98gK2GrwM0
By the way what do you think about the model picks and the recommended deck? I would be happy to discuss about it as well!

Thanks!

Got tired of clipping screenshots and writing tag files by hand, so I built this. It would also be nice to motivate more people to switch to Anima, not gonna lie :)

You hand it a video and a reference image of the character. It:

  1. Splits the video into shots, runs YOLO + CCIP, and pulls crops of just that character. Anyone else in the frame gets filtered out.
  2. Auto-tags each crop with WD14 danbooru tags and a natural-language caption (I use Gemma4 31b locally with LMStudio). The UI lets you search by tag, edit pills inline, bulk-rename with regex, re-crop, and delete the junk.
  3. Trains a LoRA. The trainer has Anima parameters already wired in, so you just have to push a button (uses tdrussell/diffusion-pipe).

Extractor and tagger are model-agnostic. Crops come out sized for SDXL-class anime models (Pony, Illustrious, NoobAI, plain SDXL). Only the trainer is Anima-specific.

A 20-min video takes around 6 minutes on a 4090 to extract the frames. LoRA training took 12 mins on a 16 images dataset.

Only the training part takes around 16GB VRAM, the rest is under 8GB All steps can now run under 8GB VRAM.

ComfyUI Workflow included in the first image.
