Secondaries...?

[Liyrex]

So i'm looking for another character to pick up and use competitively but cant really decide. Any suggestions?
I'm an aggressive lucina/marth main but all my secondaries are defensive based (Falco, Pac-Man, Robin) and i'm not sure who to go with maybe lucario/meta knight? Anyway, suggestions and insight would be greatly appreciated.
