I've thought of an idea that I think can prove rather useful.
Taking a look at Lucario, we've seen many variations from Band to Specs to the "Strike first" set I've seen (Swords Dance, Extremespeed, Bullet Punch, Vacuum Wave).
What about a mixed Scarf set? Would this be possible, and is it even a new idea? It hit me a little earlier, and I wanted to see if it's possible. Here's what I was thinking, but probably way off.
Lucario@Choice Scarf
Hasty/Naive
100 speed (to hit speed ties with Aerodactyl and Jolteon), and unsure of rest.
Close Combat
HP Fire (Skarm and Forretress)
Dark Pulse/Dragon Pulse
Stone Edge
I'm lost in the moveset and EVs, but if anyone has a clue on how this can work, please post a set.
