Ornn vs Master Yi Counter Pick

Armour is Ornn’s best statistic and this matchup ignores it. Wuju Style grants bonus true damage on basic attacks, so the 121.4 armour he carries at level 18 reduces none of that portion. The recorded result is 46.2% for Ornn across 132 games on patch 16.13.1 — a small record that indicates a trend rather than settling one.

The rest of the kit compounds the problem:

• 355 move speed against 335 lets Master Yi choose when the fight happens, and Highlander grants immunity to slows, the effect attached to both Volcanic Rupture and Call of the Forge God.
• Alpha Strike turns him untargetable while it travels, wasting a committed Searing Charge.
• Meditate restores health and reduces incoming damage, undoing the attrition a tank normally banks.
• Double Strike adds an extra hit every few attacks, accelerating everything that scales per swing.

Ornn keeps the durability lead, 660 base health to 640 and 2,513 to 2,425 by level 18, matches the 175 attack range exactly, shares the same 32 base magic resist, and swings 69 attack damage against 65, so the first levels are genuinely winnable. Both spend mana, so neither can drain the other out of resource. With ratings of 5 for Ornn and 4 for Master Yi, almost nothing here is decided by mechanical difficulty; it is decided by whether the tank forces the issue before true damage compounds.
