Once the rainbow7 organization was created, the entire roster of the old Lyon Gaming (2013) was transferred to the R7 team however, in November 2017 WhiteLotus was sanctioned until May 2018 for extreme unsportsmanlike behavior in his soloq accounts, which led the organization to hire Manu (from Predators Esports) and later Zeicro (from Just Toys Havoks). With these additions, Rainbow7 began its participation in the 2018 LLN Opening Cup dominating the regular phase by finishing in first position with 10 victories and only 2 defeats, then prevailing over Gaming Gaming by 3:0 in the best of 5 and finally beat Infinity eSports by 3:1 in the final. Achieving this way one more time to be crowned as champion of LAN and assuring his step for the Mid-Season Invitational 2018.
In May 2018, Rainbow7 leaves his trip to Europe, to integrate group A of the Play-In phase along with Ascension Gaming, Gambit Esports and Kaos Latin Gamers. Along with this, WhiteLotus completes his sanction, so the player is immediately included in the roster participating in the tournament, relegating Manu and Zeicro as substitutes. R7 debuts in the tournament on May 5, achieving a victory against the Ascension Gaming team, however in their two remaining games of the day, would not be able to win against KLG, neither against GMB. In its second day of competition, Rainbow7 notably improves its performance surpassing this time both ASC and KLG, however, to qualify for the next phase, the team should also beat Gambit Esports, where the Russian team with very good macro game, beats R7 in a very entertaining encounter, in this way Rainbow7 is eliminated in Play-In group phase with a score of 3-3 and in second place in group A.
Back in North Latin America, Rainbow7 again dominated the regular phase of the 2018 LLN Closing Cup, finishing in first position with 10 victories in front of 4 defeats, ensuring their direct pass to the semifinals, waiting for the winner of the key between Dash9 Gaming and Gaming Gaming. On September 1, 2018 and against all odds, R7 is eliminated for the first time from the LLN (as it had won all previous editions), being Dash9 Gaming who won by 3:1 against the team, this led to the dismissal of "Yeti" from the position of Head Coach for future competitions. In October 2018, LoL Esports LAN officially announced that Rainbow7 would continue to be part of the maximum category of Latin America, obtaining a place for the Liga Latinoamérica 2019. Along with this, the whole Rainbow7 organization will have to move to Santiago (Chile) to compete next year.
