9 Kings Patch 30 Deck Building and Rainbow Cards

To succeed in 9 Kings following Patch #30, limit your deck to one or two high-rarity Rainbow cards, switch to active gold-generation triggers, and draft card-draw mechanics to compensate for the expanded card pool.

Drafting and Managing Rainbow Cards

Patch #30 introduces Rainbow rarity cards as high-impact utility tools. While these cards offer significant board-clearing capabilities and resource multipliers, their high cost and powerful effects can disrupt a streamlined deck.

• Cap total picks: Keep only one or two Rainbow cards in a single deck to avoid unplayable hands and preserve core strategy consistency.
• Fill specific gaps: Draft Rainbow cards when your current army composition lacks an answer to late-game scaling or defensive pressure.
• Check upkeep: Ensure your economy can support the higher cost of Rainbow units before adding them to your draft rotation.

Adapting Deck Thinning and Gold Economy

The expanded card pool in Patch #30 makes removing unwanted cards harder. Passive income alone is no longer sufficient to afford top-tier cards and rebalanced perk costs.

1. Prioritize active gold generation: Pick units and perks that trigger gold on kills or trade loops early in a run to build your mid-game capital.
2. Draft card-cycling tools: Select cards with draw or cycle effects to increase rotation speed and mitigate dead draws.
3. Minimize inactive cards: Avoid keeping any card in your hand that fails to contribute to your combat loop within two turns.

Adjusting Perks for High-Difficulty Runs

The balance pass in Patch #30 reduces the effectiveness of pure stacking multipliers. Perks now favor flat utility, strategic positioning, and defensive resilience over raw power scaling.

Review your perk tree before committing to high-difficulty content such as King IX IX runs. Test adjusted perk combinations on lower-difficulty runs first to verify their defense and damage thresholds under current patch values.
