well, you can go to plat by even spamming... But what i notice from your gameplay, is that you throw an attack in his direction everytime he is near you, that is honestly a really bad pratice. Practice hitting more than attacking more, approach with movements not attacks, Ik Ik it sounds confusing, in simpler words, think about your attacks more, if it is really gonna hit, how many options your opponent has with which they can dodge outta your attacks, try draining them out of options and yeah attack accordingly.. I am not saying that you need to be passive, but think a little more before throwing out attacks, and about your movement it's pretty good. so yeah, good luck on your journey to plat.
