· Introducing the Dark Star Kai'Sa reroll deck, a standout in Teamfight Tactics Set 17.
· Use Illaoi as the main tank, Kai'Sa as the main damage dealer, and Riven or Karma as sub-damage dealers.
· Since this is a 3-cost 3-star deck, it's crucial to secure core champions through sufficient rerolls at level 7.

· As Kai'Sa is a skill-based damage dealer, Infinity Edge is a must. The combination of Blue Buff and Spear of Shojin is powerful due to her high attack power.
· For the remaining slot, consider items like Giant Slayer or Last Whisper.
· Recommended augmentations include Custom Revved, Assassin's Mark, Critical Success, and Will of Iron, with item-related augmentations also being useful.

· Among item augmentations, Custom Revved, Assassin's Mark, Critical Success, and Will of Iron are good choices. Bundles are also worth considering.
· Spatula augmentations are generally good, and if you're on a win streak, Urf's Gambit is also recommended.
· For combat augmentations, Boxing Lessons, Alignment, Fortress, and Black Hole are efficient. Defensive augmentations like Twin Souls and Windswept also work well.

· It's important to play aggressively in the early game by utilizing augmentations that provide extra gold.
· When in a situation where you need to lose streak, utilize loss streak synergies like Scavenger and focus on accumulating as much gold as possible.
· For the first augmentation, if you have many Giant's Belts, consider options like Rock Solid.

· Upon reaching level 7, it's crucial to secure Kai'Sa 2-star and Illaoi 2-star through sufficient rerolls.
· It's best to build Kai'Sa's core items, such as Infinity Edge, Blue Buff, and Spear of Shojin, as quickly as possible.
· If Kai'Sa or Riven frequently appear in the champion select phase, it's advantageous for completing the deck.

· At level 8, it's common to activate the Hextech synergy to increase damage output.
· If you have a Dark Star Emblem, you can grant synergy to Jin for additional damage.
· Since this deck focuses on getting two 3-cost 3-stars, augmentations like Lesser Dragon or unit-specific augmentations like Sprite can be very helpful.

· The Hextech synergy is prioritized for champions with many items. If the number of items is the same, the last champion added receives the buff.
· The Hextech synergy can significantly boost the damage output of Kai'Sa or Riven.
· You can gain an advantage in combat through the creation of small black holes and enhanced execution effects.

· Upon reaching level 8, add Riven to increase the deck's completeness.
· Since Kai'Sa accounts for most of the damage, it's important to equip her with optimal items.
· If necessary, use items like Will of Iron to consolidate better items onto Kai'Sa.

· The completed Dark Star Kai'Sa reroll deck can overwhelm most opponents with its powerful damage output.
· It's also beneficial to use units like Blitzcrank to effectively eliminate enemy tanks.
· We hope you achieve a high rank in Teamfight Tactics Set 17 with the Tier 1 Dark Star Kai'Sa reroll deck.
