Jarvan IV vs Taliyah

Plant Demacian Standard (E), then cast Dragon Strike (Q) toward it: you fly to the flag and knock enemies in your path into the air.

Land an auto as soon as you reach your target: Martial Cadence (passive) adds damage based on their current health, then only triggers on them again after a few seconds.

Cast Cataclysm (R) on a carry who is away from their team: the arena is impassable, and you can recast to collapse it if it gets in your allies' way.

In teamfights, plant Demacian Standard (E) near the allies who are attacking: it gives them attack speed while they stay close to it.

When Unraveled Earth (E) is on the ground, don't cross it with a dash or get thrown through it by Seismic Shove (W): the stones explode under you and stun you.

If you can engage, go in after Seismic Shove (W): without it, she has nothing left to push you back, and no dash to escape.

If you have CC, save it for Taliyah while she surfs on Weaver's Wall (R): once immobilized, she stops surfing immediately.
