Nasus Counters

Nasus is a juggernaut who scales with time: he stacks his Q on minions to hit like a truck late, and his W cripples a target to lock it down in fights. He is slow and vulnerable during the laning phase, before he stacks, so you stop him with early pressure that denies his farm, with ranged poke, and by avoiding the long late-game fights where his W and ultimate make him unstoppable.
