Use Jayce's ranged poke and lane pressure to deny Yasuo a calm scaling lane and prevent him from freely using (E) mobility.
Prioritize high lane pressure and tempo leads to snowball early and force Yasuo into reactive play rather than letting him control space.
Trading pattern
Use empowered (Q)+(E) poke to soften Yasuo before committing to melee trades.
Only switch to hammer form for short burst trades when (W) is down or after landing poke damage.
Punish Yasuo's cooldowns on (W) and missed (Q) tornado stacks by stepping forward for trades or wave control.
Danger windows
Yasuo is dangerous when his second (Q) tornado knockup and (R) follow-up are available; respect these windows by maintaining spacing and saving disengage tools.
Jayce is vulnerable after committing hammer (Q) engage if Yasuo counters or (W) is ready; avoid overcommitting without poke advantage.
Be cautious when mana is low or empowered (Q) is missed, as Yasuo can capitalize on reduced poke pressure.
Early game
Start with ranged form to harass Yasuo and force him to struggle for last-hits under pressure.
Avoid extended melee trades early; use (Q)+(E) poke to chip Yasuo before he can engage with (E).
Manage mana carefully to maintain poke pressure and avoid giving Yasuo windows to all-in after cooldowns.
Power spikes
Jayce's first damage item spike greatly increases poke and burst damage; use it to pressure waves and force Yasuo into defensive play.
Mid-game poke siege with empowered (Q) through (E) controls lane approaches; set up vision and fire poke before committing.
Respect Yasuo's level 2 combo unlock and level 6 (R) availability; avoid giving him clean all-in windows and punish after ult is used.
Win conditions
Use ranged poke and empowered (Q) to create health leads, then convert those leads into wave control and plate damage.
Deny Yasuo the minion wave setups needed for (E) mobility by controlling wave state and zoning.
Leverage tempo leads from poke pressure to force Yasuo into reactive play, snowballing lane dominance into side-lane pressure and objective control.
