Based on success:
SC2 Serral (won like everything in 2018 and still really good I'm pretty sure)
Dota 2 Jerax and Topson (won back to back TIs, Matumbaman good shout as well).
those are maybe top based on achievements alone and all of those 3 got invited to President's impendency day celebration.
Shahzam is of Pakistani origin but he ain't representing Pakistan lol, rather athletes like Arslan Ash the tekken player (Voted Player of The Year in the 2019 ESPN Esports Awards and the 2019 theScore esports Awards, evo championship japan and USA both in the same year)
