Wow you have a good MMR for someone who has been playing for only about 2 weeks! My internet bugged out halfway watching your video so my comment might not be accurate.

Your midline might be cheap but it can work really well if you can keep it alive for a longer time at low health since it is so tanky with a lot of shield. You tend to play your axie kisses quite early on because your team struggles a bit with damage but if you could save them until your midline is at low health you might win a lot of your games more comfortably 😄
