You have to be really careful with him. mix up both offense and defense.
Dont stay in the air too much. He can bring you down easy.Use glide tosses alot to get close. If you hit his projectiles while glide tossing, you at least have that out of the way and can dish out a grab/attack.
You have too take this fight very slow. If you lose your cool your done. Once you get hit with a Back air, DI away. Dont move into him trying to get a hit off him, cause it wont work. But if he hits you with it at a certain angle, you can N-air out of it before he gets the second in.
Turips are a must here. use them alot to get close. Use them alot to retreat. Pretty much abuse turnips when you can. But dont pick them up at the wrong time. Glide toss alot. And while retreating. Do reverse glide tosses. That helps alot.
Space like your life depends on it. Well spaced Fairs to jabs help. And get your grabs in there, Lots of grabs. Rack up damage off of them. Dont just throw him away so fast. Remember People in the game dont die off your throws. So why not built up a few more % on him then toss his azz.
Attack out of your shield alot to Nairs, Nair and Back airs. This helps with TL Up tilting you and jabbing you. As well as Nairing you.
limit your rolling as much as you can. Learn to fight on the ground alot as much as the air. Mix it up as much as possible if you feel in danger with the ground or air.
TL dies quit going up. So if you can set up kills like that go for it. Best way to kill him..
