"I can't help but say that I'm very excited to start working with my new teammates on MIBR," tarik wrote.
"The sole reason I want to make this change is simple... I want to win, and I will do anything in my power to make that happen.
"Having the opportunity to play with the legendary core of SK and reunite with my former teammate is extremely thrilling for me.
"It will not be an easy road, and I do not think we will become the best team overnight. However, I am willing to bet that we will make it work, one way or another."
tarik went on to praise Cloud9 and revealed that he always thought that he would end his career in the North American organisation, whom he had joined from OpTic in August 2017.
"To be completely honest, I thought Cloud9 would be the last team that I competed under," he added.
"They are an amazing organization that truly went above and beyond my expectations. Many people are unaware of what goes on behind the scenes, but I really want to make clear that Cloud9 do all they can for their players.
"It is very difficult for me to make this decision, but I'm confident that we will meet again at the top.
"Tim, Tyler, Soham and Will are people that are much more than teammates to me, and I only wish them the best of luck moving forward.
"The first American team to win a Major, no one can take that away from us. "
