dont have much time to write anything, but i know it's not very smart to shoot peanuts here (player 1 might disagree) cause he can shoot an aura sphere on reaction and hit you in the ending lag O.o its very scary... he can even do it when he predicts a glide toss
most of the time, the aura sphere will hit harder
and if it wasnt charged it'll at least ensure you cant follow-up
also, expect them to roll... alot o.O because its impossible to punish a lucario that rolls behind you, IF you were doing ANYTHING, so if he sees you use a Dtilt, Ftilt, Fsmash, Dsmash, (utilt and usmash not really usefull here :S) he can just roll behind you and grab
lucario's Fsmash has pretty much zero lag, he can keep spamming it just outside of your range if you dont have a banana, he can shield everything you have oos (after the fsmash) or he can roll away and punish you with an AS (if you used sideB for example)
if lucario is above you, expect the Dair (obvious FTW), but it IS possible to time a Uair between Dairs
also, lucarios trip animation is veeeery short, and if you arent fast enough, i found it actually hard to hit him with more than 2 bananas
but that can be just me...
hope this helps more than it does wrong XD
