GGs
Vantel Williams those were some fun games.
I have some advice for you as a Lucas main.
You should learn how to DJC pk freeze. It is part of why Lucas has such a great neutral game. DJC pk freeze is faster than short hop pk freeze, is lower to the ground, and is easier to follow up on. DJC pk freeze can lead into almost anything and can even combo into DACUS
You should also just learn to DJC in general. DJC magnets and aerials are great ways to shield pressure and combo
here's a vid about DJC aerials
Magnet approaches can combo into DJC aerials, wave dash back aerials, running up smash, and more so its something you should try more of. Magnets are essential to Lucas's combo game.
Also you should practice wave dashing more. Lucas has an amazing wavedash. Wavedashing out of magnet is important for a lot of followups.
Also you use a lot of dash attack which can be useful but is often outclassed by approaching magnet, fair, djc fair, etc.
There are a lot more kill options than f-smash that are more reliable. D-throw can combo into B-air for a spike or a kill off the sides or top if opponents don't DI the D-throw correctly, and sweetspot f-air, the later hits of n-air, and b-air can kill.
And lastly you should be using Jump Cancelled grabs instead of dash grabs.
LOL sorry for this big post. Just trying to spread the Lucas knowledge!
Oh and I don't have a FB sorry
