Jax Counter Champions for Jungle, Patch 15.19

Jax's early game is very strong after recent buffs; use his Q for aggressive trades to gain lane advantage. Flexibly choose runes (Conqueror, Lethal Tempo, Grasp) and items (Trinity Force, BotRK, Riftmaker), mastering his E for defense, offense, and CC. Once itemized, Jax excels in split-pushing and side lane pressure; consider hard counters like Malphite or Gragas if playing against him.
