For League of Legends: Teamfight Tactics players, picking the following Ancestral tribes during the shared draft or Ancestral Tome is a must.
The Inventor's Mark
Among the various tribes in League of Legends: Teamfight Tactics, the Inventors stand out as the most impactful. While a level 3 unit like the beetle may offer mere resilience, the level 5 Inventor bear provides substantial team damage buffs. Even at level 7, the summoned dragon wields formidable damage potential.

Expediting progress to the Inventor milestones through Heart Upgrades or Ancestral synergies constitutes a significant power boost strategy. Moreover, possessing the Inventor's Mark allows for replacing low-value units like Ezreal at the endgame with stronger pieces. This can decisively influence victory and post-match standings.
The Guardian's Mark
The greatest strength of the Guardian synergy lies in its easily activatable milestones at 2/3/4 units. Thus, the more Guardians on the board, the larger the shield they provide, rendering the composition incredibly resilient. Equipping health-boosting items makes Guardian units nearly invincible, particularly high-damage dealers like Garen.

Furthermore, Guardian-based compositions commonly employ reroll strategies to upgrade units to 3 stars. Consequently, even backline damage dealers like Caitlyn or Kog'Maw boast substantial health pools. This enhances the potency of the Guardian Mark, providing frontline units with additional defensive options and resilience against burst damage. Given these reasons, the Guardian Mark holds immense value and should be prioritized by players.
The Idol's Mark
In terms of ease of activation, the Idol synergy surpasses even the Guardian synergy. From the outset, the Idol tile grants a 20% damage boost to the unit positioned there. Therefore, players should opt for the Idol's Mark if available during the shared draft, acquiring the Idol Tome to amplify the damage output of their composition. Moreover, the value of the Idol tile increases with additional milestones activated within this synergy.

Moreover, the Idol's Mark does not dictate a specific playstyle like other Marks do and can be chosen in most matches. This is because the Idol synergy's effect complements any composition and is easily adaptable. In summary, the Idol's Mark does not disrupt a player's composition-building strategy and helps avoid getting cornered or contested for key units.
