Something I remember is that the rear hitbox of usmash is waaaay weaker, so if you do get trapped, make sure you're crossing up on him while doing so, don't get in the front of that thing.
Also something very avoidable by now, if you haven't figured it out yet, don't challenge his uair, like EVER lol. TL uair is almost like the inverse version of Link's dair, it has a lingering hitbox that retains it's killpower for a long time, and it beats out a looooot of things, easily outranges lucario dair for one, but it's very avoidable.
bomb's are kinda useful, I find myself catching them a lot. imo grounded lucario is better for this MU because it gives lucario the access to the best tool against TL: the shield.
