Last year I did a tournament with Lucario as my main and came out fourth (lost to a laser spamming fox camper) and I was quite a noob back then. Now I am going to the same school tournament to fight again. What should I do to prepare for it? I know most of MK's combos and am very aggressive while I fight. I do not have any human players to practice against. Also, when I fight I rarely use spot dodging and shields, I mostly roll. How do I practice spotdodging and shielding effectively? Is there anything else I can do to prepare? Thanks a bunch for anything.
