Senna vs Galio Counter Pick
Matchup Summary
What the Data Means
Galio brings the heavier body by some distance, 600 base health growing to 2,742 at level 18, and he attacks from 150 units. Senna works from 600. Patch 16.13.1 supplies 345 recorded games and puts Senna at 56.2% in the support matchup, graded Easy, a number that follows from where each champion is allowed to stand.
His engage is a two-part commitment and both parts are visible. Justice Punch steps back before charging and knocks up the first champion in its path, while Shield of Durand has to be charged at reduced movement speed before the taunt releases. Last Embrace answers either one, rooting the target and everything near it after a short delay. Galio deals magic damage and Colossal Smash adds an area magic hit every few seconds, so magic resistance is the buy that matters on Senna’s 30 base; his own 24 armor at level one is the soft number her mixed output can work on. Winds of War converges into a tornado that damages over time, the tool he uses to contest ground he cannot walk onto, and his 59 base attack damage against her 50 only matters if he reaches her. The ratings are 5 for him and 7 for her, which is worth stating plainly: the favoured side is also the more demanding one, and the win rate assumes disciplined soul collection through Absolution rather than a passive support pattern.
