Gwen excels as a counter-pick in the top lane; avoid first-picking her against strong counters like Fiora or Jax.
Prioritize Riftmaker, Nashor's Tooth, and Cosmic Drive, and avoid building Morellonomicon as a third item.
Utilize her W (Hallowed Mist) to block projectiles and her Q's minion execute for effective lane management.
