Jayce vs Udyr Counter Pick
Matchup Summary
What the Data Means
Udyr’s health growth is unusually poor. He starts higher at 664 against 590 and ends lower at 2,228 against 2,443, which reverses the normal expectation that a stance swapping bruiser outlasts a fighter built around ranged damage. Over 142 games on patch 16.13.1 Jayce holds 54.2 percent, a lead built on that crossover. Reaching it is the hard part. Udyr moves at 350 against 335 and attacks from 125, and Blazing Stampede adds movement speed with a stun on his first attack against each target, upgraded on recast to immunity from immobilising effects. Iron Mantle shields him and heals through his next two attacks, and Bridge Between lets him rotate stances continually instead of committing to one.
Cannon stance is the reply. A shot accelerated by the gate covers ground faster than Udyr can close it, and Thundering Blow removes him from range once he does, provided the recast on Blazing Stampede has not already been spent. Both deal physical damage, so armor is the only defensive axis that matters, and 110.9 at level 18 against 107 for Jayce leaves that column effectively level. Wilding Claw and Wingborne Storm both improve on recast, so a full rotation delivers more than any single cast suggests, and 62 attack damage against 59 keeps the early exchanges close.
