jpkurihara . Your Yoshi really needs to adapt itself. Changing strategies and not doing the same moves might help you if you don't want to be predictable.
So far, you beat me once when I was playing Mac. Little Mac isn't the easiest character to play against, even if "For Glory" tends to show the opposite. I won the rest with Mac and made one match with my Gunner and Swordsman (Hakase and Mai respectively).
You have a great character, but you always do the same strategy. You played the same for all the matches. Your moves feels sometimes random, like the Nairs that kept coming over and over, just because it's the fastest move of Yoshi with the jab. You need to try diversifying your playstyle during the match. As an example, during our first matches, I found my Mac too defensive during the match. I decided to go full aggro against you for confusion, so that you wouldn't be able to actually learn my pattern perfectly.
Maybe you should try to find a second main or a secondary. Playing Yoshi is nice, but always doesn't prepare you well. Try playing other character to find new playstyles you could try to add on your Yoshi. For example, I played Doc for a long time and switched to Mario afterwards due to his better viability. But, during my matches, if I need to play defensive, I try to put the playstyle of Doc' on my Mario, so it can confuse and help me during the match.
In short : you're a good Yoshi player, but you need to not repeat yourself.
Otherwise, good games dude, keep playing !
