Build and Runes
Don’t stand too close to enemy tower when pushing so that Alistar won’t be able to use Flash pulverize into headbutt combo.
Punish him hard for messing up a Headbutt – Pulverize combo.
Unless it’s a certain victory, try not to dive an alistar because of his ultimate and his insane CC.
Forcing Alistar to use his heal often in lane will drain his mana, leaving him unable to CC you with his other abilities.
Don´t stand together in lane because Alistar could try to kick away the Support to knock up the ADC and initiate a fight.
Take advantage of Alistair’s huge cooldowns early if he headbutt/pulverises your support or ADC you will have about 8 seconds before he can do anything!
