Alistar vs Senna Counter Pick
Matchup Summary
What the Data Means
Alistar wins just 44.5% of the time against Senna on patch 16.13.1, and with 1,595 recorded games behind that figure, it is a large enough sample to trust without much caveat. Range explains most of it. Senna fires from 600 units, one of the longest ranges in the game, while Alistar has to close 475 units of empty space before Pulverize even threatens her, an approach she can poke down freely with Piercing Darkness the entire way.
Senna’s passive, Absolution, lets her farm souls from any unit that dies nearby, scaling her damage and range further as lane goes on, so the range gap only grows worse with time rather than closing. Last Embrace also roots at long distance if it connects, which can lock Alistar down before he ever reaches auto-attack range in return. Both champions carry a 7/10 difficulty rating, so neither side has a mechanical execution edge, the deciding factor is that Senna’s kit was built to punish exactly the short-range engage supports Alistar depends on. Senna mostly wins this lane by never letting Alistar get close enough to play his kit at all. Her title, the Redeemer, and her role as a hybrid marksman-support give her the rare luxury of full poke potential from the safety of the support position, a combination few other bot lane champions can match.
