StageFavouredWhy

Level 6SwainLevel 6 favours you: Demonic Ascension heals through and survives his all-in, punishing his engage.
First itemEven / skillFirst item is even: your burn sustain trades roughly with his Locket-boosted engage utility.
Two+ itemsAlistarTwo-plus items favour Alistar: Locket and R let his W-Q engage lock you down and burst before your drain wins.

How to beat Alistar as Swain: the early game

You own levels 1-2: E Nevermove root plus Q Death's Hand out-trades anything Alistar can do before he has his full combo, and he has zero poke to contest your lane presence. Zone him off the caster minions and freeze the poke advantage. Ward the tri-bush so a flash-W engage can't catch you flat-footed. Everything you do starts with the root, so hold it for his approach rather than throwing it at the wave. Stack the bolts on him afterwards and let the soul fragments pay back whatever his combo takes off you before your carry follows up.
