How the Team Building page is built

Where the data comes from

The Team Building page is built from game data for the current Teamfight Tactics set. The effect text, rarity and the stages where the augment is offered are refreshed with every patch. When a tier letter is shown, it tells how strong Team Building is in the current meta.

What this page shows

The card at the top shows the full effect of Team Building, its tier, rarity, type and the stages where you can pick it. Right below are similar augments of the same type, stronger ones first, so you can see what to take instead. Further down are the strongest comps, items and traits of the set.

Augment strength depends on your board, stage and economy, so treat the tier as a guide and check the effect against the comp you are playing.
