You outrange lucario in the air and outrange everything but fsmash on the ground.
If you grab lucario you can keep pummeling over and over until he ground releases and regrab him, he can roll out of it but then that becomes a tech chase.
Jab and fair cancel auraspheres nicely.
Eh I find the match up pretty easy :/.
lucario's roll is a tool in this matchup. Marth approaches from the air, ROLL, grab or whatever cario wants besides slow stupid sideB that yall love.
Also, your fsmash outranges Marth's SH->whatever, therefore its your anti-air attack. And it kills marth stupid early.
Cario's fair might not have as much range as marth's but it is a free kill if you catch marth in air anywhere near the edge after his double jump. Just fair fair fair fair fair fair till death. Lee has caught me and roy and dphat and several others with these shenanigans. Really, range isnt EVERYTHING.
and PLEASE, that grab release is hardly matchup-breaking. The most marth can hope for is like 14 damage TOTAL from it. I mean, D3 has a tech chase on GW, is the matchup in D3's favor? -.-
I agree marth should win, but it's definately not a shutout.
