I'm new to learning how Lucario works. What are the bread and butter combos I should be using in general? Also, how do you cancel the charging aura into a usmash? Does Lucario have any kill throws (similar to what Ness has)?.
Lucario can make nice combos with Fair and Uair (and easily at low %). And generaly you can start them from Up throw.
For the Up Smash, you need to cancel the charging aurasphere with shield, then cancel the shield with a jump, and then again cancel the jump with the Up smash. You need to do it very fast, the input when you are charging aurasphere are (with no tap jump) : Shield → Stick Up → Jump → A
Lucario don't have Kill Throws, but maybe sometime back throw can kill with high % aura and with the opponent with high % too
