Thanks for trying it out, sorry you're having trouble! Are you playing on web? Could you send me a screenshot so I can see if it's something the game renders wrong or if it's too small cause of the resolution or something else?
Yes, a way to zoom into a single card is planned, which will also show more explanation of the mechanics and key words. Coming soon™✌️
When a card has "etheral", it means it will be destroyed instead of going (back) into the deck. So for example, if you see a flipped Ruby, you might wanna pick it up or it's gone :)
