Join a team with good experience and alchemy, practice a lot and do some tournaments online first.
Then maybe offline events.
Entry frager or whatever you need.
I think that there is much we can say in a description, but for me the best way to know ambitions of people is to talk with them and play few games together.
Im back on the game since a long pause, 5k+ hours. Ive already done a few Offline events with mix team, but now im searching for a team and for some consistency of training with people who love the game.
Good vibes and thirst for victory.
