While playing the new RPG from mihoyo (genshin impact's creators) Honkai Star Rail, I chanced upon this weapon with effects that made me think of AST's cards.

In this game there are 7 different 'paths' that gacha characters can be, one of them being 'The harmony' that are pure buffers.
'Weapons' in this game give special effects to the character wearing it similar to how they work in genshin impact.

It made me think of an idea for AST's cards.
Obviously the game I mentionned is turn based so it wouldn't work with FFXIV, but the core idea behind it gave me an idea. Also don't pay attention to the part where buffs are for the whole party. The cards would still be single target.

Give AST new cards, all with a different effect, similar to old AST but that would work with the current expansion. It doesn't need to be 6.
Make it so that you cannot draw the same card that you last used along with a redraw. That would make it impossible to fish for balance while also giving you a redraw to pass a card you don't need at the moment.

It's a minimal rework so it wouldn't alter the job's playstyle much while giving the same flavor that old AST cards had (without the fishing for balance bit).
It also gives room to rework Astrodyne into something more interesting that could play around this.

My only worry is that because of the 2 minute meta utility cards would be frowned upon.
