I didn't really see him spamming, but I've seen his other matches, and I gotta say, that TL is a beast. Lol at johns, like 5 of them.
Work on your spacing. You have to take a hit every now and then to start some combos. Think about it would you rather be hit with an arrow or a banana? I'd rather be hit with an arrow. However, don't take the bombs, because bananas get neutralized by them. Boomerangs are easy to avoid. Also instead of rolling try some dribbling to avoid the zair. He had a very effective zair game. Try to say about 2-3 body lengths away from TL. He can't really spam the boomerang as much and zair is too short to reach you. The only thing he can do is Arrows and bombs, while you have bananas. I dunno what else to say. Also if you are up a stock on TL you can easily do 40-50%. TL's kill moves are predictable. Fair, Uair (so easy to predict), Fsmash (lol) and Usmash. The only thing to watch out for is the zair to (move) and fair. Usmash is their main killing move so you know they are always going to try that.
