All the cards unlocked after the tutorial are added to your collection, but not to your deck. The cards you unlock as you level up from 1 to 10 are part of the core set for that class and you will have all the necessary cards to create the core deck for that class upon reaching level 10. The core deck is a 30 cards deck that should be a lot better than your starting deck and more than enough to allow you to defeat all expert-level opponents without much difficulty once you get more familiar with the game.
While deck building is not available yet, you should be able to get someone to help you or use OCR to create it if you've reached level 10. Here's a list of steps if you'd like to give it a try: 1. Click the "My Collection" button near the bottom of the screen in the main menu. 2. Find the "New deck" button. There's a vertical scrolling menu at the right containing all of your decks. The "new deck" button will be the last button so you may need to use the mouse wheel to scroll down if you've already unlocked all the classes as you'll have a bunch of decks. 3. Click the "new deck" button. 4. Click the hero you'd like to create the deck for. There's 10 different portraits and you'll hear the sounds as you hover them with your mouse. Click the "Choose" button somewhere at the bottom section of the window at the right. It also has a sound effect when you hover it. This will open a menu with 4 premade deck recipes that you can pick from. 5. Click the one at the left: this will read something like "Core Rogue." 6. Click the "Choose" button somewhere at the bottom. 7. Click the "Done" button close to the bottom right. You're done! You can now click the "Back" button to get back to the main menu or simply restart the game. Your deck will be named "Core something" depending on what class you chose and you'll be able to select it in practice mode.

The mod is and will always be free for everyone. Patreons and donators don't get any exclusive perks: they simply support me so I can dedicate more time to working on this as opposed to doing other paid work. To give you a simple example as I've been asked about this more than once: if a given game mode takes me 80 hours to complete and I were able to work 8 hours per day, 5 days per week on it, it would be released in 2 weeks. Since I do have bills to pay and a family to support however, I may only be able to dedicate 1 hour a day to this after work, which means it would take 4 months instead. As soon as something is done, it'll be released for everyone at the same time though.

I naturally can't answer for Blizzard here nor know what the future holds, but for whatever is worth I've been developing the mod without ever getting banned for several months now which means I access the game multiple times per day every day and have played hundreds of games while developing and testing new features. It's also worth keeping in mind that none of this is offline. Tutorial games, practice games and solo adventures are all online. The AI opponents you play against are on Blizzard's servers. You cannot play the game offline at all.

You don't need to run the patcher everytime. The mod will warn you whenever you're loading the game if a new version has been released. The only time you will be forced to run the patcher is when Blizzard updates the game as you will lose accessibility after the game is updated to the new version. This normally happens every couple of weeks and I do need to release a new version everytime so you may need to wait a few hours depending on how busy I am at the moment. Feel free to send me a direct message here or anywhere else if this happens just in case I haven't noticed it as I don't have a way of knowing when Blizzard updates the game.
