New Feature: Shards (Patreon)

🎉 Introducing Shards! Ⓢ Use these to permanently upgrade the Rarity of Cards. 

Upgrading "Common" Cards to "Uncommon" or "Rare" is cheap, but getting them to "Mythic" will need a lot of Shards. 😳

💭 Learn more in the Card Details view, then look for the button next to 'Upgrade Proces'.
