TCG Frame Removal LoRA (FLUX.2-Klein 4B)

An instruction-editing LoRA that strips the frame, text, and UI elements from trading-card images (Magic: The Gathering, Pokémon, Yu-Gi-Oh!, Digimon) and extends the artwork to a seamless full-bleed illustration.

File	Base model	Recommended sampling
`lora_klein4b.safetensors`	FLUX.2-klein-base-4B	20–25 steps, CFG 4.0, empty negative

Usage

The input card is passed as the control/reference image (kontext-style edit conditioning) and the prompt is the edit instruction. The instruction is game-specific — use the exact phrasing the LoRA was trained with (shown with each example below).

Cards come in a variety of aspect ratios and the LoRA was trained at each card's native size, so generate at the input image's own dimensions (rounded down to a multiple of 16) rather than a fixed resolution. A subset of the training pairs was padded to a portrait / 9:16 ratio, so padded inputs are handled as well.

Python example (MTG)

python

import torch
from diffusers import Flux2KleinPipeline
from diffusers.utils import load_image

pipe = Flux2KleinPipeline.from_pretrained(
    "black-forest-labs/FLUX.2-klein-base-4B", torch_dtype=torch.bfloat16
)
pipe.load_lora_weights("lora_klein4b.safetensors")
pipe.enable_model_cpu_offload()  # fits in 16 GB VRAM

card = load_image("mtg_card.png")
width, height = card.width // 16 * 16, card.height // 16 * 16  # match the card's own size
prompt = (
    "Remove the title, mana cost, type line, rules text box, power and toughness, "
    "and set symbol. Paint over those areas with a natural continuation of the "
    "existing artwork."
)

image = pipe(
    image=[card],
    prompt=prompt,
    guidance_scale=4.0,   # true CFG with an empty negative prompt
    num_inference_steps=20,
    height=height,
    width=width,
    generator=torch.Generator("cpu").manual_seed(42),
).images[0]
image.save("full_bleed.png")

For the other games, swap the prompt for the matching instruction below.

Before / after examples

All examples are held-out validation cards (not in the training set), generated at 20 steps, CFG 4.0, empty negative, 848×1184.

Magic: The Gathering

Prompt:

Remove the title, mana cost, type line, rules text box, power and toughness, and set symbol. Paint over those areas with a natural continuation of the existing artwork.

Pokémon

Prompt:

Remove the card name, HP, energy type icons, attack names and damage, weakness, resistance, retreat cost, set number, and illustrator credit. Paint over those areas with a natural continuation of the existing artwork.

Yu-Gi-Oh!

Prompt:

Remove the card name, attribute icon, level stars, card type line, ATK and DEF values, effect text box, and outer card border frame. Paint over those areas with a natural continuation of the existing artwork.

Digimon

Prompt:

Remove the card name, level indicator, attribute icon, type bar, DP value, play cost, digivolve costs, effect text box, and card border. Paint over those areas with a natural continuation of the existing artwork.

Training

Dataset: 547 curated (input card → de-framed full-bleed) pairs across the four games, teacher-generated with Qwen-Image-Edit-2511 and manually curated. Captions are the edit instructions above. Pairs keep each card's native aspect ratio (it varies by game), plus a subset padded to a forced portrait / 9:16 ratio. The full training set is published at pearsonkyle/tcg-frame-removal-dataset.
Network: LoRA rank 64, alpha 32, on the transformer only.
Recipe: trained with ostris/ai-toolkit at lr 1e-4, bf16, flow-matching with weighted timestep sampling. The 600-step checkpoint was selected by held-out evaluation — later checkpoints did not improve.

Known limitations

Cards with non-standard layouts (full-art EX / promo Pokémon cards, some Yu-Gi-Oh! frames) may keep their inner border or art box instead of extending to full bleed (~3 of 24 held-out cards).
Output has a mild painterly softening versus the original art crop.
Card art is owned by the respective game publishers; this LoRA is intended for research and personal use on imagery you have rights to process.
