You used a total of two flashes over 20 rounds, one which was horrible, and one that only displaced a single person, which also had no followup. YThe Omen blind is an amazing tool to get kills, take space, and for many other things, and you could have easily made it a lot less difficult for yourself and your teamates if you just had used them correctly.
You used a total of 6 shadesteps over 20 rounds, 4 of which had no effect, or a detrimental effect. You played 2 vertical angles (the same angle), using your shadestep. In my opinion, the only shadestep that was truly useful was the one on B site when you used it in your lurk smoke to take space toward garage. However, I did not see you use your shadestep to break timings, to relocate after fights, to play strong vertical angles, particularly toward mid, nor any other tps into smokes to get onto site.
You used your ult one time in the entire match, which accomplished nothing. You did not use it to get into angles where the enemy did not expect you, you did not use it to break of the rotate on attack, you did not use it to get info.
I would recommend you try to get more used to Omen utility in general, because right now you are play Brimstone without stim and molotov.
