Pick Swain as a counter-pick, strong against melee-heavy compositions but weak into ranged teams.
Prioritize Rylai's Crystal Scepter for ultimate synergy, then build tanky items like Rod of Ages or Abyssal Mask.
Use your E skill to poke or catch enemies trying to last-hit minions, and always take Conqueror rune for sustained fights.
