I was surprised that the U-smash finally did the trick O_o. I thought I still had another 10-15% to go.
Falcon is becoming more and more fun for me to use, since I can land knees semi-consistently now, like in that match where I landed 4 of them, two of which in a row <3 I was able to get a Grab release -> Knee on a Wario main a few hours before I played you too. Also, U-air is awesome. Too bad I fail at offstage kills.
Your Lucario's fine, but he got kind of telegraphed over time - Aura Sphere camping when I was on the other side, f-tilt, F/D-smash, or jump -> n-air when I got close, rush to the other side, and repeat. But I'm no Lucario expert, so that may be the best course of action.
But the more I play Falcon, the more I begin to see what TheReflexWonder meant by his mobility.
