Estral Esports was the most dominant team in Latin America during the early days of Valorant winning First Strike in LAS (LAS has always been performing better than LAN). When they first formed they also played the then dominant Brazilian juggernaut of Gamlanders close 11-13 and 12-14 in some best of ones. Three of those players are now playing in Champions for 3 different teams.
Saadhak in Vikings, Nozwerr in Furia, and NagZ in KRU.
(The other two are a coach and player for 9z who scrambled their roster too late to get enough points for the Latin American qualification to Champions).
I don't think this team would necessarily be as successful today or as good as KRU, but Argentina and Chile have produced a surprising amount of good players.
