Anivia

Anivia is an AP mage in the support, and on patch 16.17 they grade out as a solid mid-tier pick — a 49.6% win rate, 0.5% pick rate, 5,268 ranked games sampled. On the power curve, Anivia is a scaling champion: comparatively weak early, but one of the strongest picks on the map once core items come online — so the plan is to survive the laning phase and take the game over late.

How Anivia wins: grouped 5-v-5 teamfights, where Anivia tips the fight, and winning the wave and turning push priority into map control. The kit grades 9/10 teamfighting, 9/10 waveclear, 9/10 disengage. Anivia grades low on engage and roaming (3/10, 2/10), so don't take fights that turn on those dimensions.

The most-played core build is Zaz'Zak's Realmspike, Rod of Ages, Liandry's Torment, which holds a 49.8% win rate across 223 games this patch. The build above re-optimizes once you lock in the enemy composition.

The matchup to respect is Tristana, where Anivia sits at just 43.0%, the lane swings the other way into Yone (55.4%), and on the team side, Anivia gains the most from a Gangplank (+9.8% pair win rate).
