Mastering Sword Boomerang, Warcry and Necronomicon! - The Slay the Spire Mastery Challenge

In 2023, I created the Slay the Spire Mastery Challenge, embarking on a quest to master every single card and relic in the game - including curses and special relics!
A card is mastered by winning an ascension 20 heart run with at least two copies of it in the permanent deck at the end of the run.
A relic is mastered by winning an ascension 20 heart run while having the relic.
Here, you can watch my journey on the way to becoming a Pokemon Spire Master!

The mod I used to track mastered cards is available on the steam workshop: https://steamcommunity.com/sharedfile...
