How the Polymorph page is built
Where the data comes from
The Polymorph page is built from game data for the current Teamfight Tactics set. Wisps are the Set 18 mechanic, so the effect text, rarity and the stages where Polymorph is offered are refreshed with every patch.
What this page shows
The card at the top shows the full effect of Polymorph, its rarity, category and the stages where you can pick it. Right below are similar wisps of the same category. Further down are the strongest comps, items and traits of the set.
Wisps are not ranked by tier, their strength depends on your board, stage and economy. Check the effect against the comp you are playing.
