Senna vs Anivia Counter Pick

Equal attack range removes Senna’s usual advantage. Both champions fire from 600 units, so the exchange turns on what each does with that distance, and Anivia’s answer is the harder one to play around. Senna wins 45.8% across 273 tracked matches on patch 16.13.1, and the model grades the support matchup Hard, which fits a champion whose safety net is a full-health revival.

• Rebirth turns a first death into an egg with full health, so burst that would remove another support only removes a cooldown.
• Crystallize raises an impassable wall, cutting the retreat path Senna needs after committing Last Embrace.
• Glacial Storm and Frostbite punish anything already chilled, and 530 base health with 30 magic resistance is a thin buffer.

The counterweight is cost of execution. Anivia is rated 10, the ceiling of the scale, against Senna’s 7, and she carries the softest armor line of the pair at 19 rising to 88.7, with 325 movement speed against 330. That argues for early pressure: Piercing Darkness trades before Anivia has the mana and levels to hold Glacial Storm, and Absolution keeps collecting souls from a safe position. Both spend Mana, and her damage is pure magic, which at least makes the defensive purchase obvious. Flash Frost is also a slow sphere that can be sidestepped at 600 units, the one skillshot Senna can dodge without surrendering her own trading distance.
