Patch 12.19 can be considered one of the most important updates for Teamfight Tactics season 7.5. Many champions, traits, and systems have been rebalanced and reworked, making the gameplay of this game incredibly exciting. Among them, the Shadow Dragon Gemstone composition has emerged as Shi Oh Yu and Syfen, the two key champions, have received significant buffs.

Essentially, the Shadow Dragon Gemstone composition has become powerful because it can be effectively used against any opponent. While Shi Oh Yu counters melee champions, Syfen excels at eliminating backline champions effectively. Therefore, you can use this composition in any match with extremely high effectiveness.
To start with this composition, you need to have at least one Jax champion after the first three rounds. This champion is a very annoying tank and helps you maintain health effectively in the early game. You can even combine Jax with three Dragon champions including Skarner, Nidalee, and Vladimir to improve your gold income in the early game.

When you reach level 6, you should add other Dragon champions to activate the 3 champion bonus as soon as possible. With a 2-star Nidalee holding the items of Shi Oh Yu and benefiting from the Dragon statue effect, you will have a very strong carry.

By the late game, you should look to replace the Dragon champions with Shadow champions like Syfen and Pantheon. Of course, Shi Oh Yu is a must-buy champion to reach the 5 Dragon threshold. Additionally, Jayce should also be prioritized at this stage as he provides good area damage and the Guild effect gives considerable armor and magic resistance.

For the augment choices, Treasure and Pandora’s Bench are the options you should take when playing the Shadow Dragon Gemstone composition. Essentially, both Shi Oh Yu and Syfen have strong target execution capabilities, making them very suitable for the Treasure core. Moreover, the Pandora’s Bench core will help you increase the chances of upgrading your Divine Dragons to 2 stars and securing victories.
For item choices, Bloodthirster and Giant Slayer are suitable items for both Shi Oh Yu and Syfen. Additionally, you can craft defensive items for Jayce to buy more time for the two carries mentioned above to deal damage.

Conclusion
Essentially, the strength of the Shadow Dragon Gemstone composition comes from its overall balance in both offense and defense from Shi Oh Yu and Syfen. If you are looking for a fresh yet effective way to climb the ranks, then the Shadow Dragon Gemstone is an incredibly wise choice.
