Duelist of the Spire

Slay the Spire 2 meets Yu-Gi-Oh! Master Duel. Every card and monster is read live from your own Master Duel install: names, art, Level, ATK and DEF.

The Duelist

• A new playable character with a deck of Classic and GX era cards: Dark Magician, Blue-Eyes White Dragon, Elemental HEROes, Pot of Greed, Mirror Force, Polymerization, Dark Hole and more.
• Five monster zones. Summoned monsters attack a random enemy at the end of every turn for damage based on their ATK, and summoning gives you Block based on their DEF.
• Tribute summons. Level 5-6 monsters tribute 1 monster, and Level 7+ monsters tribute 2.
• Fusion from the Extra Deck. Avian + Burstinatrix makes Flame Wingman, Sparkman + Clayman makes Thunder Giant, two Blue-Eyes make Blue-Eyes Ultimate Dragon, and more.
• Graveyard and Monster Reborn.
• Starting relic: Heart of the Cards, which draws 2 more cards at the start of each combat.

A Spire of summoned monsters

Every act's fights become Master Duel monsters with their real art, and their HP and attacks come from their DEF, Level and ATK. The bosses are Blue-Eyes White Dragon, then Elemental HERO Neos, then Dark Magician.

Needs

• Slay the Spire 2 (Steam).
• Yu-Gi-Oh! Master Duel (free on Steam), installed and opened once so its card data is downloaded. It doesn't need to be running.
• Single player.

The first time Slay the Spire 2 loads a mod on your PC, it asks once whether to enable mods and then closes. Press Play again.

Nothing from either game is included: the mod reads your own copies. Built with Claude (AI). LZMA decoding by the LZMA SDK (Igor Pavlov, public domain).
