You should choose the cores below to be able to climb better in the Tactics Arena.
Mysterious Heart
Before version 12.14 was released, this was a technology core with the lowest pick rate in the Teamfight Tactics. The reason for this came from the fact that at that time there were too many formations that dealt strong physical damage, so the magic resistance that Mysterious brought was not too valuable. Moreover, the situation of fighting for Upper Dragon is not too fierce, so Nami can swing out easily, so players often skip this core to get other more valuable upgrades.
Owning one more Nami for free is extremely important in 12.14
However, when update 12.14 reduced the power of a series of physical damage and magic mains to the throne, Mysterious Heart suddenly became extremely powerful. Giving the whole team a small amount of magic resistance will help your mainstay survive against Aurelion Sol, Sona or Anivia. Moreover, the current situation of competing for Upper Dragon has become too fierce, so owning Nami for free is something extremely valuable that you should get.
Nhat Thong
If you pay attention a little, the Arena of Truth season 7 has a lot of generals with 3 races – systems. Even the number of clans – systems with conditions to activate few champions are relatively large, so the fact that a level 8 squad can own 6-8 clans – system is a common occurrence. This makes the Unification core (which provides attack stats for the whole team based on the number of races – activation system) extremely powerful and useful at the moment.

Even according to statistics site Metatft.com, Nhat Thong II core is also the upgrade with the highest average position of 3.89. It is not exaggerated that every time you choose this core, the gamer will firmly hold a position in the last 4 players group and have a ranking score. So if you see the Unification core appear and the squad can activate multiple races at the same time, choose it immediately. This is an upgrade that will help gamers own a very strong squad in the late game.
Ventilation
After 12.14 was released, we can see that the game speed in the first 4 stages is no longer so fast. The reason comes from the fact that a series of squads that rotate a lot to get 3-star champions early have been heavily nerfed and players will often be more towards the late game. This makes the tech cores that provide the experience boost for players who reach level 8 or 9 early to be incredibly powerful.
Going to level 8 as early as possible with the Clear core and then turning to Aurelion Sol will help you win very easily.
Among them, we must mention the Clear core when it gives you 3 free experience per round if there is no champion in the queue. Simply put, you will sacrifice upgrading 1-2 money champions to 2 stars in exchange for leveling up quickly. This is a huge advantage because the strength of the current Dragon God generals is extremely superior, owning level 8 before the opponent will help you turn out these generals much easier.
