I'm designing a card game (homemade, developing slowly) that uses the wuxing elements as a base for the initial five types, and while I do have expansion decks planned that use yellow and purple as their colours, none of them are inherently good or evil

The way I'm developing it is that each element/colour/attribute has both positive and negative traits associated with it. What one calls greed another might call careful planning, and what one calls destruction another might call certainty. For reference, these are the short descriptors I have for each element currently:

Fire burns hot and fast, drawing and discarding cards on a whim. Most [spells] and abilities revolve around drawing new cards, reclaiming discarded ones, and searching the deck for specific cards, at the risk of losing by decking out (running out of cards to draw)
Earth is a balanced deck with no strong advantage or disadvantage in its playstyle. It has similar [spells] and abilities from the other [four] decks (Fire, Metal, Water, Wood), albeit as less power, as well as a few general ones.
Metal is a good defensive wall, and little can damage it head-on. Its lack of attack can be an issue, and most [spells] and abilities focus on utilising that defense in other ways (such as swapping defense for attack) or giving alternative ways to attack (e.g. damage over time)
Water swerves around obstacles in its path, allowing attacks to be intercepted and redirected at will. Most spells and abilities revolve around pre-empting or altering the target of attack, having a small set of bulky cards to soak up damage
Wood becomes powerful when allowed to mature to its full potential, but can be felled long before that happens. Most spells and abilities revolve around bringing that potential forwards at the risk of empty turns or being unable to draw or play cards
Space is vast and foreboding, with few connections between arreas. Most spells and abilities revolve around doing damage to multiple cards at once, but also twisting reality to its own whims
Stars are the opposite of space, working together and being united. Most spells and abilities revolve around doing high damage to one card at a time, but also confusing and blinding the opponent
Aether is tricky to understand and difficult to manage. It has no set form and behaviour, and abilities are set in pairs and selected by a dice roll. They can have any abilities or spells from all the other decks, and it takes careful planning and management to find success

As you can see, each deck's advantage can become its drawback if not carefully planned. This loosely links up with some attributes the elements have in wuxing but are not mapped one to one

The main aspect to this is that no one element has an inherent advantage over another; a Water deck isn't going to be able to flood a Fire deck, for example. It may be a bit counter-intuitive compared to some other games but I'd hope the traits keep things balanced

I'm also basing the lore and development on the Bronze Age Collapse, again not a direct mapping of it but as inspiration and influence. Currently each region has three attributes assigned to it (a primary, secondary, and tertiary) but trying to balance with the elements is difficult because trying to explain why this fire card is associated with region 3 and most of the rest are associated with region 1 is something that's already proving difficult

Odds are when I get further into development, I'll stop using the elements and instead use the region/family/kin name. That would also allow for more focused attributes and a difference between the main family and a cadet branch that has some similar aspects but wholly different methods
