Josedeodo's Monster Kick! Lee sin W trick.
They replayed it, and Caedral also looked into it in the linked video, but they didn't really mention the cool mechanics he used to pull that kick off. In real time, when I was watching, I was surprised by how fast he pulled off that kick, and it looked almost buggy. I realized he used the W trick in Leesin, where you can input ult and spells mid Q2 dash if you W someone into Q2 while mid W dash. This is probably the only reason Berserker and Vulcan can't instantly react to the Leesin. It made his kick flash instant.
A similar mechanic was used in the famous Canyon kick. He ws ambessa into q2 kick flash on Berserker all while he is traveling in the air.

Jose played out of his mind that series, and I wanted to highlight a sick play with more depth than people realize. The presence of mind to pull this off in basically the fight that will decide the game is so insane.
