A pre timeskip One Piece tarot deck needs to exist, Luffy follows the fools journey so well. My idea for how it could go:
0 The Fool: The barrel at sea luffy was floating in.
Perfect for the inexperienced fool
What more can I say to that one , zoro has luffy's back, starting the crew and conquering hardships.
2 The High Priestess: Nami
Directions, man , what's better than the navigator herself.
3 The Empress: Sanji ( bear with me on this one)
This man's whole thing is admiring beauty, being in love, and being compsionate to people. Even if the card is feminine, he embodies it pretty well.
4 The Emperor: Usopp (again, bear with me on this)
His whole thing is that he wants to be a brave warrior of the sea, he may be a coward but he's strong when it counts to the people around him.
5 The Heirophant: either Smoker or Arlong
I feel like either of them could work to show the crew their first glimpse at the bigger scope of things.
6 The Lovers: the Going Merry
It's the best choice when it comes to signifying the relationship the crew has and the love they have for one another.
The idea of the chariot is success won't come if thinking is limited, Crocodile embodies that incredibly well when they're first introduced.
She's had to be a very resilient person throughout her life and act courageously in some of the toughest times.
Early Robin is very much the Hermit prefering solitude and figuring out things on her own.
10 Wheel of Fortune: Zoro and Luffy Facing Bellamy that first time with Blackbeard there
This feels like the Wheel of Fortune. I don't quite know how to describe it like the feeling that anything can happen in the future.
11 Justice: Cp-9, franky, and Robin
That whole arc was past actions coming back around.
12 The Hanged Man: Robin wanting to live
That small action paved the way for so much in the story it was also Robin letting go of the solitude and moving forward.
13 Death: The Going Merry sinking
Need I say more on this one.
The man needed to accept that he was gonna be part of the crew.
15 The Devil: " nothing happened"
That scene and zoro's choice to keep his captain from being caught feels right for this card
16 The Tower: Ace's Death
Luffy's lowest point , where everything collapsed because he wasn't strong enough in that fight, and where he realized he needed to train if he was going to get any further.
Healing and hope, man, Law came in at the right time for this one.
18 The Moon: Luffy mourning Ace's death
This was a really uncertain time for him and quite possibly the only time I've seen him even think for a moment about giving up.
He helped Luffy through that uncertainty by reminding him of the people that care about him.
20 Judgment : telling his crew to train for 2 years
This was a big moment of Luffy thinking of their past and future and what his crew needs.
21 The World: everyone meeting back up
They're ready to take on the world and all its challenges.
