Galio vs Senna Counter Pick
Matchup Summary
What the Data Means
Two very different profiles meet in the Support lane: Galio the tank/mage hybrid, Senna the support/marksman hybrid. The sample behind this page is 355 games from patch 16.13.1, and Galio wins 43.9% of them. That is 6.1 points under even, which is why Senna is listed among the champions Galio struggles into.
The 600-versus-150 attack range gap means Senna can contest the wave from outside Galio’s reach. That forces Galio to play around cooldowns and pathing rather than raw stats.
Galio threatens Hero’s Entrance; Senna counters through Last Embrace. Then it becomes Hero’s Entrance against Dawning Shadow, and the one still holding it sets the terms.
Both Galio and Senna threaten mainly magic damage, so one resistance covers the lane. Before items it is 600 HP, 24 armour, 32 MR for Galio; 530, 25, 30 for Senna. By level 18 that becomes 2742 health and 104 armour for Galio against 2043 and 93 for Senna. Base attack damage is 59 against 50, so Galio wins the raw auto-attack exchange. Movement speed: Galio 340, Senna 330.
That 43.9% rests on 355 recorded games from 16.13.1.
