We have a thread on secondaries. I don't know who uses Villager and Falco and frequents the boards here... FOW uses Villager and Ness - don't remember which he mains - and he has used Falco before in the 3DS days. Maybe even continuing since he dittoed Cyro. I do know
@Gamegenie222 has fought Villager a lot, though. He also plays Rosalina, Robin, Roy?, and either Lucina or Marth along with Falco.
Using Villager for campy MUs... Falco's kind of designed for anti-zoning while Villager's more for zoning... Well, he would be doing a better job if his Blaster wasn't just "functional". For some, Falco's also pretty decent against Captain Falcon, Fox - basically Ken vs. Ryu or maybe Iori vs. Kyo -, and even Sheik, but that's all you as a player and how you deal with things. If you're looking for speed to deal with moving through projectiles while having projectiles of your own, Sheik, ZSS, Pikachu, the Pits, Greninja, Diddy, Fox, Yoshi, Toon Link, Mario, Wii Fit Trainer, and Sonic - he's a living projectile after all - come to mind. For more slower paced while having (an arsenal of) projectiles, Link, Samus, Luigi, Dr. Mario, Olimar, Mega Man - really good air speed, though -, Pac-Man, Rosalina, Lucario, Mewtwo, Mr. Game & Watch, Duck Hunt, Peach, Ryu, ROB, Ness, Lucas, Robin, and Bowser Jr. come to mind. Out of those options, the Pits and Mario are the most balanced choices. You don't really sacrifice much like or have to deal with a lot of issues like the intricacies of Ryu, Pac-Man, and Peach, having worse recoveries with Ness, Dr. Mario, and Luigi, having kill issues now like Duck Hunt and Yoshi, or having similar issues due to similar physics like Fox.
Now, if you're just looking to break zones and rush in, without projectiles, Captain Falcon, Roy, Marth, Meta Knight, Little Mac, and Sonic. With projectiles, you're looking at Fox, Greninja, ZSS, Sheik, Yoshi, and Pikachu. Ike, Wario, and DK are pretty much worthwhile, but outlying characters as they have issues with projectiles as well, but Wario always presents a threat since Waft charges passively.
