Card Effect Suggestions
If you don't like the bonus Tarot Cloth effect of one the cards, let me know here. My goal for these new effects is not to alter the card's base effect or provide an OP effect, but to give the player a thematic advantage that is equal in power to the Tarot Cloth effects for the base game.

Please include:
- The name of the card
- The new effect (if you come up with one)
- Your reason for why you dislike the current effect / think your idea is better.

For example:
The Moon: Spawn a portal to the Super Secret Room.
Reason: The current effect isn't as thematic as my idea

Sun Card: Removes all curses
Reason: Honestly the current effect doesn't really feel strong enough for tarot cloth.

The Moon: Sends you to the Super Secret Room
Reason: Duh.

For The Sun, I like your suggestion of just having it remove all Curses. It'll be an easier effect for the player to remember as well and I don't think it's too OP.
For The Moon, I didn't want to alter any of the cards' base game effects, and I felt teleporting to a different room than usual might not be what the player wanted when they used the card.

I was going to suggest having sun card remove curse of the lost and curse of darkness instead of curse of the lost and curse of the maze, but having it remove all curses definitely makes the tarot cloth investment more worthwhile

Good to know! The Sun without Tarot Cloth actually already removes Curse of Darkness, which is why I made the bonus effect remove other curses.

Don't get why Reverse Emperors effect is locusts, but if the idea is something to help with the boss fight why not just a Black Heart just like how Emperor is a Soul Heart.

Reverse Devil could be something related to giving an Eternal Heart or giving a temporary Eucharist alongside it which would be nice for getting Angel Rooms after a Devil room. Just another familiar is kinda eh imo.

Thanks for the suggestions!

I can see your point about Reverse Emperor's effect, My reasoning for the locusts was that I wanted to give the player an offensive advantage to mirror The Emperor's effect, which gives the player a defensive advantage with the soul heart. I'll consider giving the player a black heart instead.

As for Reverse Devil, I like your idea about increasing the Angel room chance while it's in use, I think giving a few points to the Angel deal seems good.

The difficulty with Reverse cards is that in the base game, there is a bug where Reverse cards are actually quadrupled in effect with Tarot Cloth instead of just doubled. So do I balance the new Reverse effects around being double power, or copy the base game and make them quadruple powered? Right now I am choosing to balance them around only being double power, because I assume eventually the base game bug will be fixed. That's why I'm hesitant to make effects too strong, since the base game effects of Tarot Cloth are also pretty underwhelming.

I think it would be cool if Moon and reverse Moon gave you golden variants of the pickups instead. Just giving you a bomb/key is a bit boring compared to the other effects, and getting a rare golden bomb/key doesn't seem too op

@MisterKaze That's a good suggestion. I was originally basing the power of The Moon cards off of The Lovers with Tarot Cloth, where you get 1 extra heart drop as the bonus. As I get more feedback from players, though, I feel like the people who downloaded the mod expect a bit more power than just getting 1 extra pickup. I like your idea as it is still simple, just a bit more powerful than the current effect.

the world card should show all red key rooms too, or maybe just the first layer if that's too op.
the emperor? should also spawn a devil/angel room too instead of the locusts, or maybe double the items instead if thats too op. i think those would both be pretty cool

Thanks for the suggestions!
For The World, I like the idea of revealing the Ultra Secret Room as well, since that is the most valuable Red Room to find, but revealing the entire Red Room map would probably just annoy the player (since it is unlikely that they could access the Red Rooms and it would make their map way bigger). You're correct that revealing only a single layer of Red Rooms would be too challenging for me to code.
For The Emperor?, a guaranteed Angel/Devil room or even a guaranteed extra boss item seems too OP to me. The original Emperor Tarot Cloth bonus is a single soul heart, so I tried to make the bonus for The Emperor? be around that level of power.

I recomend to swap the Moon and Moon? effects so Moon gives the key and Moon? gives the bomb.

Moon? can soft lock you if the way back involves a secret room and you have no bombs, this prevents that + Gold bomb's are inherently a lot stronger than Gold keys which mirrors the power difference between Moon/Moon?

Thanks for the suggestions! I'm also not happy with the current effect of The Moon (getting golden bombs so easily is very powerful, as you said).
The original reason I had The Moon give bombs and The Moon? give keys was a) for thematic reasons, but also b) because using The Moon? already gives you an Angel item, so I thought giving golden bombs on top of that would be too much. I also didn't want to give actual consumables when using either card, because their Blank Card charge is only two rooms and that could create a situation where the player could farm for bombs/keys by repeatedly using the Blank Card.
Long story short, I like your suggestion more than the current effects, even if we lose a little theme. However, I'm thinking about just having both cards give the player two bombs and two keys the first time it is used per floor: yes this would make their effects identical, but golden consumables are just so powerful. We'll see.

I've got some ideas for The Moon cards. I'm not sure about The Moon? yet, but the regular moon card effect could be to simply give you the I Can See Forever effect so you can effectively get to both the regular and Super secret rooms without an awkward double teleport. Maybe both moon cards do that so the reversed one is just better, but I could understand wanting them to be distinct. I've also read other people suggest the Luna planetarium effect for the floor you use it on if possible, which may also be a consideration if you wanna put I Can See Forever on the reverse Moon. Thanks for making this mod!

Thanks for the suggestions, these are really helpful! Those darn Moon cards have proven to be quite annoying for me to design effects for.
I like the idea of giving the player the Luna effect for The Moon, I need to do some more research to see how to replicate this effect with the current modding API.
I still want to give the player bombs/keys for the Reverse Moon, since Ultra Secret Rooms almost always require bombs/keys to access the item. I'm fine leaving the Tarot effect for Reverse Moon pretty low power, since the card itself is already OP and making it twice as OP with Tarot Cloth seems unnecessary design-wise.

My suggestion for the Moon cards would be that they work in a similar manner to The Stars. For The Moon, if the Secret Room hasn't already been entered, it guarantees that an item pedestal is spawned (if the room doesn't contain one by default).

The Moon? would instead cause two item pedestals to spawn in the room, but allow only one to be taken. If getting a choice of two angel items is too powerful, the second item could be from the Old Chest pool instead (the flavour text is "May you remember old memories" after all). Another idea for The Moon? is that it could spawn two eternal hearts on the floor in the Ultra Secret Room.

For The World, I had the following ideas:
- Invoke the Soul of Cain-effect (open all red doors in the room).
- Give the effect of "I can see forever" + remove Curse of the Lost.
- Reveal the current floor's treasure room item above the player (similar to the dream catcher's effect).
- Chance to spawn a copy of the card in the starting room of the next floor.
All of these, except for the last one, fit the flavour text ("Open your eyes and see") in my opinion.
