Track: Jax's E — Counter Strike (17–9s cooldown). Dodges autos + stuns. Bait it.
Read from Jayce's seat: which stage windows this plan plays for against Jax.
This is Jayce's own plan; across 1,368 pooled games the lane is leaning Jayce.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Jayce | You take Cannon-form Shock Blast at level 1 and out-range a melee Jax with no Counter Strike yet -- free gate-Q poke on every last-hit step-up. |
| Level 2 | Even / skill | You add Acceleration Gate for the full accelerated orb, but Jax also has his early points and dodges with Counter Strike -- the poke edge is real yet genuinely contestable here. |
| Level 3 | Jax | Jax's Counter Strike comes online: it blanks your Hyper Charge autos, and standing inside its radius gets you stunned into Leap Strike + Empower. |
| Levels 4-5 | Jayce | You still own the pre-item poke war -- both stances online, his items absent, so trade around his Counter Strike cooldown and stack the health lead. |
| Level 6 | Jax | Level 6 is a non-spike for you (the stance swap is not a new ult) while his R is a real burst of resists and on-hit damage -- any all-in he survives now is his. |
| First item | Jax | His Trinity Force or Blade of the Ruined King plus R lets him eat the orb and stat-check you -- your squishy first-item frame loses the extended duel. |
| Two+ items | Even / skill | Two items in it is a knife-edge: your banked early lead versus his hard on-hit scaling decides it, so the game must already be ending on your terms. |
Cannon-form Q is your whole opening -- take Shock Blast at level 1 and gate-Q his step-ups before Jax has Counter Strike to answer you. The moment you hit 2-3, the accelerated orb through Acceleration Gate plus the cannon-swap first-hit Armor/MR shred chunks anyone who walked up to last-hit, so make him choose between farm and face. The one trap: at level 3 Counter Strike is up, and while it cannot dodge Shock Blast it does blank your Hyper Charge autos -- stand inside its radius and the recast stun feeds you Leap Strike + Empower. Poke from max range, swap to Hammer only to Thundering-Blow a committed leap out of range, then swap back to re-poke.
