Early game (levels 1–5)

Kassadin is one of the weakest laners in the game before 6 and you punish that. He has no waveclear and no mobility, so shove with Steel Tempest, use Sweeping Blade off minions to close, and poke him off the wave every time he steps up to farm. Keep the wave on his side and make him miss CS — every level here is tempo he can't recover once his scaling starts.
