Hello NationalArmy!
First of all, you really should join the Faeria discord channel if you havent already! You can access it from your friendslist.
There is a lot of activity there and most of the time I can chat with my opponent there. That might be even better than having an ingame chat, because sometimes I really want to talk about the game with my Faeria-friends without having to launch the Faeria client!
Maybe there is a way to combine the two?
Personally I am not sure if I want to have an ingame chat (except with people on your friendslist).
A daily puzzle quest sounds like fun! That would absolutely make me want to login every day! Not for the reward, but because puzzles are so fun 
For ingame tips, many of the “Puzzles” in Solo-mode is more about giving you a lot of tips in an interactive environment, than actual puzzles. It would be great if you could play them without having to unlock them though 
About improved wording for cards, check out this post Oracle Text for all cards
Is there any card in particular that you feel have bad wording? The only card I can think of right now is “Doomgate, Door to Oblivion”, its a card with very little information about what it actually does, but it is intended. Its supposed to give you this “OH WOW OMG!”-feeling when you procc it 
Good feedback! See you in discord
