probably tenz, really bad 2023 and heading into 2024 he was able to prove everyone wrong and even won a trophy while at it. other than that i would go with kangkang, meteor, t3xture, boo
t3xture: from mediocre results on GE in 2023 to winning Shanghai in 2024 + Madrid Finalist
meteor: same thing as t3xture but on GenG before their rebuild, also won Shanghai alongside t3xture
Boo: From being one of the worst EMEA teams in 2023 to leading his team to two international finals (they lost but who cares) back to back
