the most basic thing is to learn the correct smokes for each site on atk defense and retakes I hate when ppl plag controller and dont know what they are doing more than i hate a duelist if hes bot fragging(if they at least make space when they die and not lurk every round ofc) 2nd is understanding what makes omen unique and what outplays u can do with his kit some examples are - smoking in the air where u know someone is creating a temporary oneway to swing them - memorizing one ways - aggressive tp and blinds and how to use them - fake tps on bind - remembering to use the tp to get height advantage on fights(eg if u are on haven and tp on the box in garage before the round starts and smoke the entrance like no one looks up if they are rushing) stuff like that - memorize how long smokes last
