Hi Stashinko!
We actually discussed this after we finished our most recent stream since someone watching brought it up! To keep the game simple, the card game is somewhat abstracted. While you as a player only have 4 cards in the deck, the character you play has a full sized deck and their plays with the deck are represented not just by the cards in your deck, but also by your staples and many of your combat based moves. There's nothing stopping the cards you play from representing multiple cards in your characters deck!
For an effect like Exodia, we recommend thinking about how Exodia actually "plays" as an effect! Most decks that use Exodia focus on either draw or stall engines, depending on how your deck wants to use this style of effect, you could make a card that says "when I draw this card X times I win the game" (remember that you can reshuffle cards from your graveyard into your deck) or you might create an Item that represents the engine thats letting you draw exodia that says something like "Roll 1d4 at the start of each turn and put that many counters on this card. If this has 12+ counters, you win the game".
We give a lot of recommendations in the full book for ways to achieve some of the stranger TCG archetypes, so hopefully most of everything should be covered in the full release! (And if we missed something, our community should be knowledgeable enough in the tools of the game to help out!)
