Teamfight Tactics Season 15: Tier 1 Comp Guide Compilation (Viego, Jinx, Kai'Sa, Rammus, Yuumi, Jhin)

We analyze the major Tier 1 decks of TFT Season 15, providing key strategies, item builds, operation methods, and placement tips for each deck. We introduce how to win in ranked games through various decks such as Viego, Jinx, Kai'Sa, Rammus, Yuumi and Jhin.
🛡️Soul Fighter Viego Deck
The 8 Soul Fighter Viego carry deck prioritizes Viego 3-star, with Guinsoo's Rageblade, defensive items, and Jeweled Gauntlet being key. We recommend a build-up using Giant Beast, and at level 7, form a combination of 6 Soul Fighter + Udyr, and at level 8, 6 Soul Fighter + 4 War Machine. We recommend Elastic Arms as Viego's power-up.

✨Star Guardian Jinx Deck
The Jinx value deck builds up based on Poppy tank items and Jinx damage items. Utilize the Gnar power-up (Golden Spatula, Recurve Bow, True Damage), and when re-rolling at level 8, fix the core 7 units and add Fortress/Sniper. For Jinx, we recommend White Mosquito Jinx (Guinsoo's Rageblade, Shojin's Spear) and Stormcaller Jinx, and add Gnar in the final level 9 combination.

⚔️Mentor Kai'Sa & Kobuko Reroll Deck
The Mentor Kai'Sa & Kobuko Reroll Deck adds Heavyweight and Brawler champions if there are no Mentor champions at level 6, and maximizes Supreme Cells synergy by adding Akali at level 7. Equip Kai'Sa with Infinity Edge, Shojin's Spear or Guinsoo's Rageblade, and Titan's Resolve or Deathblade/Giant Slayer, and Kobuko with all defensive items. Aim to get Kobuko and Kai'Sa to 2-star after reaching level 6 in round 3-2.

🦏Rammus Kai'Sa Reroll Deck
The Rammus Kai'Sa Reroll Deck operates by switching to Rammus when Lulu appears early, and rerolls at level 6 to aim for Rammus, Kai'Sa, and Darius 3-star. If Akali appears quickly, switch to level 7 and utilize the 4 Supreme Cells synergy. We recommend Gargoyle Stoneplate for Rammus and Shojin's Spear for Kai'Sa.

🐱Prodigy Yuumi Deck
The Yuumi deck is centered around Yuumi, and Yuumi has the highest win rate when she doesn't have mana items. Augments like Overachiever or Pandora's Items have a high win rate, and Leona is given tank items such as Gargoyle Stoneplate. Reach level 10 and add Seraphine.

🎯4 Bastion 5 Sniper Jhin Carry Deck
The 4 Bastion 5 Sniper Jhin Carry Deck utilizes units such as Malphite, Jinx, and Varus, centered around Jhin. The early build-up utilizes Crew, and prioritize making Malphite 3-star at level 5. Give Jhin Guinsoo's Rageblade or 3 damage items, and Malphite various defensive items.

🌟Mentor Ryze Senna Deck
The Mentor Ryze Senna Deck utilizes Mentor synergy centered around Ryze and Senna. Equip Ryze with Archangel's Staff, Titan's Resolve, and Void Staff, and Senna with Titan's Resolve, Shojin's Spear, and Deathblade. The level 8 composition consists of 4 Mentors, Giant Mech (Jarvan, Aatrox), Senna, and Akali, and Lee Sin is added at level 9.

🐛Bastion Kog'Maw Deck
The Bastion Kog'Maw Deck has high stability due to its synergy with the 'Caregiver' power-up. Kog'Maw has a small mana pool, so items like 'Shojin's Spear', 'Archangel's Staff', and 'Guinsoo's Rageblade' are very efficient. Put Kog'Maw in 6 Bastions, and after getting him to 3-star, add Jarvan or Ryze.

🦋Bastion Xayah Rakan Reroll Deck
The Bastion Xayah Rakan Reroll Deck is a level 6 core deck composition based on Bastion synergy, utilizing Xayah as the main dealer. Equip Xayah with Guinsoo's Rageblade, Kraken Slayer, and Infinity Edge, and Rakan with Bloodthirster, Archangel's Staff, and Spirit Visage. Reach level 6 in round 3-2 and proceed to make Xayah and Rakan 2-star.

🏹5 Sniper Jinx Deck
The 5 Sniper Jinx Deck utilizes Braum, Gnar, Jhin, Caitlyn, Jinx, and Varus as the final level 9 composition. Prioritize crafting Jinx items, and there are two versions: Guinsoo's Rageblade version and Shojin's Spear version. Reach level 8 in round 4-1 and reroll.
