Blademaster is a powerful melee composition in Teamfight Tactics Season 7, boasting formidable close-quarters champions.
Throughout the evolution of Teamfight Tactics, melee champions have always been an integral part. In Season 7, Riot even introduced a composition called Blademaster specifically to bring these close-quarters champions into the game. During the testing phase, Blademaster compositions gained popularity for their formidable strength. So, what makes this composition strong? Let's explore.

Fundamentally, the Blademaster team's playstyle is easy to grasp, with its main champions, Olaf and Yone, having straightforward abilities. Their strength primarily comes from regular attacks and the incredibly potent damage amplification of the Blademaster composition. Not stopping there, Yasuo, a 5-cost champion, is exceptionally powerful in the late game with high mobility, ensuring that the Blademaster team doesn't face a decline in strength as the match progresses.
The basic strategy for Blademaster is to roll slowly at level 6 to upgrade Yone (and possibly Shen) to 3-star to become the carry. In case you reroll at level 6 but find many Olaf units (5-star and above), the advice is to push to level 7 and use these units as carries. Since Yone and Olaf use the same type of items, you won't have to worry about wasting items when combining them early on.

By using two different carries, the Blademaster composition is often divided into two playstyles: 6 Divine (with Yone as the carry) and Dragon's Claw (with Olaf as the carry). For the 6 Divine team, you will use Daeja and Yasuo at the end of the match to activate this synergy. For the 4 Dragon's Claw team, you can add units like Diana, Lillia, Braum, and potentially leverage items that increase skill damage for these champions.

The weakness of the Blademaster composition lies in having all champions excel in melee combat. Consequently, this lineup struggles when facing teams with excessive crowd control. Particularly challenging are matchups against compositions with abilities that slow attack speed, knock-up effects, and broad-spread damage like the Crystal Desert synergy, making it difficult for the Blademaster team to secure victories. The inclusion of champions like Ngoc Long's Ashe, with attack speed reduction, and Shi Oh Yu's knock-up and substantial standard damage, serves as a solid counter to this team composition.

In summary, the Blademaster composition is an easy-to-play and straightforward team comp. Its sole weakness lies in susceptibility to crowd control effects and potent area-of-effect damage abilities. To address this vulnerability, equipping Quicksilver Sash on key champions becomes imperative when fielding this lineup in the battles of Teamfight Tactics Season 7.
