Some people in the LBR need to learn how to fight Diddy and Falco as those are completely even matchups.
Then let's start talkin' about them. That's why I posted it here, so we can keep on movin' forward in these MUs.
I feel Diddy is still 55:45 us and Falco is 50:50.
If you trade hits from a nanner and a BAS Lucario will do more damage and have time to get up. Diddy can become more aggressive horizontally in the air, but spaced right our FAir will hit without trading.
You can grab Diddy out of his Dash Attack and FSmash. Diddy's DSmash comes out in 6 frames, so grounded Luc's DSmash is a bad idea.
Diddy's first and second hit of his Dash Attack has 6 frames of blockhitlag and 1 frame of blockstun. This means you have a four frame window to grab him (the last frame you will take damage, but still grab due to grab armor).
Diddy's FSmash first hit has 2 frames of blockstun and 6 frames of blockhitlag so between hits you have a 5 frame window (11 frames total) to grab him during his FSmash.
Diddy's UAir comes out in 3 frames.
Diddy's Fair comes out in 6 frames.
Diddy's BAir comes out in 5 frames.
Diddy's DAir comes out in 13 frames.
Diddy's Jab comes out in 3 frames.
Diddy's DTilt comes out in 4 frames.
Diddy's FTilt comes out in 10 frames.
Diddy's UTilt comes out in 6 frames.
Even though he's faster than us in the air we have our disjointedness.
Diddy's kick from his side B comes out as early as frame 16.
Diddy's facehug grabs on frame 19-32 of his side B.
Either way that gives you more than enough time to evade it (roll), but if we're all frame perfect our FAir will not hit him before his kick comes out.
Just be weary of Diddy's 6 frame UTilt when you're like 170%, as it will kill you. I remember ADHD spammed that when I was above him in a WiFi set.
I think that if we Lucarios played this particular match-up more patiently we'd do better.
