If gamers can successfully pick the tech duos below, their team composition in Teamfight Tactics will vastly improve.
Duet of Divine Echo and Sharing Glory
With the current dominance of Kai'Sa in the meta, the Divine build has become exceptionally favored in the current meta of Teamfight Tactics. With significant increases in damage, energy, and health regeneration, the Divine build can elevate not only Kai'Sa but all main carries significantly. With just one Divine slot, the power this build provides is already formidable, but having two cores of the Duet of Divine Echo and Sharing Glory can amplify this even further.

Basically, when owning both cores of the Duet of Divine Echo and Sharing Glory, gamers will possess numerous Divine slots on the board. It's important to note that the effect of the Sharing Glory core will provide all champions around the Divine slot with an additional 500 health. This enhances not only the main carries but also the tanky and support units, making them more resilient and capable of dealing better damage. Truly, if you have both of these tech cores, you're almost guaranteed a spot in the top 4.
Pandora's Box - Scouring for Treasures
Teamfight Tactics: The Everlasting Importance of Equipment

In Teamfight Tactics, building team compositions based on the items you receive has long been the optimal strategy. Being able to combine 'disruptor' items for tanky units, damage dealers directly influences the ranking results of gamers. And in season 6, you can easily do this through 2 cores of Pandora's Box - Scouring for Treasure.
Trade Hub - Golden Ticket Shopping
Compared to the two pairs mentioned above, the chances of owning the tech duo Trade Hub - Golden Ticket Shopping are the lowest. The simple reason lies in the fact that the Golden Ticket Shopping core is of Diamond rank with an extremely low appearance rate. However, when you own both cores, you can save a lot of gold for rerolling as the Trade Hub allows you to change the shop for free once. With the Golden Ticket Shopping core, you'll have a chance to get another free reroll.

Although not directly providing power, with the ability to reroll multiple times and save a significant amount of gold, gamers will have the opportunity to upgrade their team composition higher than other players. Especially in the late game when you need to spend all the gold you have to complete your team composition, the combination of the two aforementioned cores will help players reach the level of the main carry more easily. Therefore, these two cores are suitable for every playstyle, whether it's budget-friendly (Tristana, Twitch) or expensive (Urgot, Jhin...).
