Karthus into Master Yimedium

Overview

Prioritize full clears to leverage your superior clear speed and avoid early duels with Master Yi.
Avoid early river fights unless lanes have priority to prevent getting punished by Master Yi's resets.
Scale through farming tempo to unlock global pressure with and influence fights remotely.

Cycle camps efficiently to reach level 6 and your first AP item faster than Master Yi.
Contest river vision and Scuttle only when lanes can move first to deny Master Yi safe objective access.
Trade camps cross-map when Master Yi attempts early invades, avoiding direct fights until you have item spikes.

Vulnerable during early clears before level 6 when Master Yi can invade and force you off camps.
Isolated river skirmishes are risky if lanes lack priority or vision control.
Objective setups without vision or lane priority expose you to forced smite fights and Master Yi's reset potential.

Start full clear away from river entrances to minimize early invade risk from Master Yi.
Only contest first Scuttle if nearby lanes have priority and can assist in counter-ganks.
Track Master Yi's pathing closely and avoid low-health river entries vulnerable to his medium dueling threat.

At level 6, use to influence fights globally and finish low-health targets.
After your first AP item, increase camp cycling to arrive at objectives first and punish Master Yi's weaker early fights.
Respect Master Yi's level 6 and item power spikes by avoiding extended low-health fights and holding CC for his engage.

Convert faster clear speed and item spikes into early objective control and vision dominance around dragon and Rift Herald.
Use after fights start or enemies drop low to secure kills and snowball map pressure.
Deny Master Yi free farm by tracking his path and counter-jungling when he overextends or resets inefficiently.
