How to Play This Matchup
Early Aggression
Olaf needs to punish Master Yi before they scale. Zone them off CS levels 1-5 and look for solo kills before first back. If Master Yi reaches 2 items even, you're in trouble.
Armor Rush
Both champions deal physical damage. Whoever builds armor first (Plated Steelcaps, Bramble Vest) gets a huge advantage in trades.
Exploit Olaf's Weakness
Olaf's main weakness: Kiting after R ends, falls off late. Play around this to maximize your advantage.
Olaf Win Condition
Run people down with R CC immune, lifesteal at low HP
Master Yi Win Condition
Scale, Q resets in teamfights, R makes untargetable
Ghost Threat
Olaf runs Ghost  they can run you down in extended chases. Respect their movement speed and don't overstay in trades.
