Card Mastery

This mod adds a system inspired by Monster Train to Slay the Spire! Introducing Card mastery.

When you beat the Heart all the cards in your deck are mastered. This has no gameplay impact, it's simply a set of customizeable visual changes that allows you to keep track of what cards you beat the game with. It might even encourage you to take cards you normally avoid for a bit of extra spice in your runs!

So, what exactly are these visual effects? The card backs are changed to a nice gold with velvet text area (thanks to Laugic maker of the Vacant for the art!), cards have a nice little shine effect and you can see the highest Ascension the card was mastered on when looking at the big card view. Best of all, they're completely customizeable. In the config menu you can toggle each feature individually or enable the gold card back for curses.

In case you don't want certain to show any mastery effect, you can hide it individually in the big card view.
There are also three commands:

1. mastercard [cardID] [number]: This command doesn't give you free money, I'm sorry to say. Instead you can set the mastery level of a card.
   
2. clearmasteries: CAREFUL. This command gets rid of all currently saved mastered cards in case you want to do a full reset.
   
3. unmastercard [cardID]: This command removes the mastery of a single card.

You can enable "Require 2 copies for mastery of a card." in this mod's mod config menu to do exactly what it says on the tin in case you want mastery to be a bit harder to achieve.

Thanks to JackRenoson the velvet of the mastered card backgrounds is now colored according to the character's main color (Silent has green, Watcher purple, etc), this can be disabled in the options menu.

Finally, I've released a texture replacement for the card backgrounds made by Alison, maker of the m10 Robot and more using Kiooeht's newly released Texture Replacer mod. You can copy that and modify the images within to customize the look of the card backs easily as well.
