So first this is a great time. I beat my first run with it and my second on ascension 1 as well as many rush runs which were intentionally lost just to find cards and I wanted to give some feedback and wait to play again till more work is done. To note I have not tested your mod at higher ascension levels so things I might find need balance may be wrong in that it loses a lot of value at later stages. Another note I have yet to find 1 rare card. It is a blue one and my guess is maybe it is a card that works better the more water you have up.

Good:
- The resource system is great. The fact that cards can have various effects is a cool design and gives a psuedo ice cream effect.

- The starting deck actually feels pretty good and useable something I was scared about with it not being the standard strike defend set up.


Balance:
- The starting deck is really good actually. A bit too good. I had no reason to be scared and the starting deck allows you to really abuse the first level and take on as many elites as you want. As well if you get at least alright deck do the same on the second level.

- Astral Form+ is really powerful (being specific with the upgraded form). This card basically makes it so you don't need to worry about all the elements. I spend 1 element and boost 2 others (or the same element). The moment I have this card I will sit at +10 for every element every combat as long as the combat isn't over quickly. This really takes away from the resource management your mod is looking for. As well makes your cards like Ignition that rely on high element totals really powerful and really easy to play for big hits. What I would suggest is instead of making it produce 2 elements having it cost 1 for the upgrade that way it is a easy to play resource generator, while the other specific forms can be your high in one resource generator. Another thing could be to make it a higher rarity card because currently it is the only reliable way to get resources to a high level. However, currently I think the character needs the card in its current state because element generation without it suffers.

- Reckless dance generates you way too much dexterity. It has literally the smallest downside being the possiblity of taking 3 damage over 2 turns, but can generate you so much dexterity till you get to the point that its generate you so much you can't use the ability. And since its a skill you can keep using it over and over again for even more and more dexterity gain till you are unhittable. The card is just so powerful for what it does. Best card by far.


Bad/Can be improved/Bugs:
- Stone to Mud doesn't get dexterity buffs or suffer from frailty. It will only generate 5 block no matter what. It will show the value as if it does, but then gain 5 anyways

- Momentum Doesn't always generate you an extra point of elemental energy for your second energy gain.

- it crashes a fair bit. Most likely because it isn't built for the current version of STS and I didn't downgrade.

- If you save and quit mid combat all of the element generation cards change what they generate (something I discovered because of the crashes). This might lead to a lot of save scumming by people, but idk if this is fixable.

- The rune generation card (forgot its name) when it generates will put the runes into your discard pool if your hand size is big enough. If this isn't intended I would suggest making you pick a rune like you would pick a power with the power potion

- The cards have so much on them. I'm reading a lot when I play this character. Near every non starting card has at least 4 lines of text and many have 5 or 6. You don't really have any simple cards.

- All of your elements are pretty straightforward and don't have a lot of variation to what they do. Fire does a lot of damage, Earth defends and does a little bit of other stuff, Water Weakens stuff and heals, and Air draws and gives dex. Your elements don't do a lot else and it makes runs a bit repetitive. So as you make new cards I suggest really diversifying what the elements can do.

- Everything revolves around the elements. Maybe make something that doesn't. Like how Defect has claw and all for one not revolving his orb mechanic.

- There is a lot of zero cost cards. And I just spam these to generate more elements in early combat. I especially spam them when I have astral form+ so that all this spamming just nets me more energy as well as mist. So yet again when you're making new cards maybe look to not increase the zero cost card pool too far.

- I would love to see a fire X element cost card. However if that is made ignition would for sure have to be nerfed in its fire generation.


Also I really understand this is a WIP so don't feel like I hate your mod. I really like it actually and see that it has a lot of potential and I hope you can make it really great and can't wait for the next update to it.

Edit* added some more feedback
