To be fair, we always use third party code when generating bitcoin wallets and things.
That's the whole point of this thread - not using third party code to generate your entropy.
That's what I was confused about when you acted like I was using Deckware to generate entropy. Deckware doesn't do that. Shuffling the cards does that. Then you just use Deckware to convert your card order into a hex string. The raw entropy was created by the physical act of shuffling the cards. Deckware is just a tool to transform that raw entropy into a hex string. But it's not really adding to it or removing any enotropy from it.

The whole point of generating a seed phrase is that seed phrases are easy to back up. Storing a deck of cards in a particular order is an incredibly risky idea. Anyone who finds it might use the deck without realizing what it is. You yourself might forget it is in order and absent-mindedly use it or shuffle it. Even if you are clumsy or slip when removing it from the packet and drop a few cards, or even if one end of the packet unexpectedly pops open, good luck trying to access your wallet again.
Yes you are right about the cards slipping out of ones' hand and that could cause a disaster. Had that almost happen to me because new cards can be slippery and so you're right about that issue. There is a fix for that though, if you take a magic marker and mark a big X along the width of the card deck. That way they could be put back into order. Never tried it but I heard about that trick. problem is if you do that then you can only do it once obviously.

This is a mindset I have always disagreed with. People create all kinds of stupid methods for generating wallets. The most recent one I remember commenting on was using emojis, with people defending it by saying "Well, it's just for fun!" Even if the author created it "just for fun", there is a not insignificant chance that someone will use it and end up losing all their coins.
What do you think about a little bingo machine that has a bunch of balls in it numbered like 1 to 80 or something? I think that could be a good way to generate entropy. It rolls them all around inside the cage and takes one out on ever turn. I'd be willing to put my life savings in it for a few days that's how confident I would be in the quality of the raw entropy it provides. Same with dice rolls or maybe even a card deck. I'm not dumb. Grin Thing is, with that little bingo cage I still havent figured out how to convert the result into raw entropy but I think it would be similar to the card deck but not exactly the same since there are more than 54 bingo balls...
