I'm not a pro, but I can certainly give some tips!

Inscryption is an amazing game, but I find it hard to understand what's going on a lot of the time. Slay the Spire is much better in that regard. You can hover over any status effect, keyword and so on to get a tooltip that explains things pretty well. Most artifacts etc. are also easy to understand, and the tutorial is a good introduction.

Some tips (most are good for all such card games):

• The most important thing after immediate survival is synergies. Find cards and artifacts that work together. Focusing on individual cards is usually harder to bring to a win.
• To be able to reliably draw your synergies, try to keep your deck lean. Focus on removing cards that you can "replace" with better versions (e.g. basic attacks/defends). Also don't add willy-nilly if you have a good thing going, try to think about what you're lacking.
• Focus on getting cards/artifacts/synergies that allow you to draw more cards & generate extra action points.
• Sometimes, taking a bit of extra damage early can save a lot of extra damage later.
