Their Sky — Idle Deck-Building and Automated Conquest

Their Sky blends idle mechanics with strategic deck-building. Rather than playing every move, you design decks and automation rules that run themselves, battling online, pursuing missions, and chasing rewards. The core idea is to craft automated strategies that steadily advance your collection and climb the leaderboard, even while you’re away.

As you expand your card collection, your decks gain power and flexibility. With a growing library of cards, you can assemble meta-defining combinations that adapt to different matchups. The game rewards thoughtful construction, clear automation logic, and data-driven decisions, providing a satisfying path from early builds to top-tier strategies.

• 300 powerful cards to create diverse, overlapping strategies and synergies.
• Full automation rules that let you automate any strategy, from fast-against-starters to patient control loops.
• Playback of all automated matches for reviewing, testing, and refining your approach.
• Leaderboard with rewards to measure progress, compete against others, and earn seasonal incentives.
• Missions that reward card packs, accelerating your collection expansion.
• Challenges that grant rare cards to strengthen your top decks.
• Full card analytics to study performance, win rates, and matchups to optimize future builds.

How it works is straightforward: you craft decks and automation rules, let the system run battles online, and then use playback and analytics to iterate. Each win, each pack, and each rare reward feeds back into stronger decks and smarter strategies. The automation-centric design keeps the game accessible while offering deep, long-term strategic depth for seasoned players.
