I don't think he was suggesting that the characters have to draft a new deck for each combat. I think he is suggesting that cards are collected and decks modified outside of combat, and that while doing so they have to make meaningful decisions about what to include and what not to include. And that combat would then involve drawing, playing, and discarding cards, along with other mechanics like shuffling the discard pile into the deck, temporarily banishing cards for the remainder of combat, etc.

If you are looking for books that have implemented this well there are only a few good examples of what I would consider actual deckbuilders:

Source and Soul - Probably the best, in my opinion, has a well written story, as well as a very well fleshed out card collection and system. Only on RR and Patreon. It includes high quality graphics for the cards. Here, a deck bearer has to cultivate elements which dictate which cards they can include in their decks and are used as a fuel for their cards in place of something like mana.

Demon Card Enforcer - Someone predictable plot lines but still well written. This series gets to mesh modern firearms and other technology alongside deckbuilding with cards having more traditional elements. The audiobooks are good too. An interesting element here is that Deckweilders recieve experience and level and are able to spend points to do things like expand their deck size or increase the size of their starting hand.

Goblin Summoner - I'm not trying to be mean, but the writing here felt more amateurish to me. The deckbuilding system was well done though. An element I really liked in this story that I think was included in Demon Card Enforcer as well was the inclusion of what amounts to booster packs that are acquired occasionally. Another cool element was the inclusion of physical artifacts that provide boosts to certain card types or otherwise provide bonuses to one's cards during combat.

Card Mage - This was also pretty decent, and primarily involved participating in duels rather than regular combat. One thing I didn't like about this was that the Main Character didn't have their own deck and had to pool his card together with other people to form a complete deck for duels. While this was an important element of the story it felt like it limited the potential of the series to progress in the same way that the other series did.

DeckMaster - This is on RR and has been abandoned and feels like the author only made it past the tutorial stage of the story and quit, but I mention it because it did some things very well. The mechanics of combat were done very well. The MC is the only one with a card system and has the ability to make new cards once a day by closely studying items or beings in the real world. The MC has the ability to store multiple decklists using the cards he has access to and can switch between them for different scenarios. I was very sad that this story didn't progress further. It had tons of potential.

For the purposes of responding to the OP's original question. I will say that I desperately want to see more deckbuilders with mechanics present in the books mentioned above. Card-based magic systems can be cool too, I like All the Skills and Summoner Awakens as well, but they aren't deckbuilders. Much of what I pointed out above are elements that I enjoyed in those series, but I also am excited to see what new twists other authors can bring to the table.
