Villager has a lot more two-move conversions than long combos.
Here's some setups into grab that I use:
lloid projectile > grab
lloid ride > footstool > lloid aerial momentum cancel > grab (only works on some characters)
weak dair > grab
jump lloid projectile (to block jumps) > grab
Throw options
Down: aerial followup (percentage dependent)
Up: tree plant or retreat
Forward: tree plant or retreat
Back: KO at ledge (on Wii U), low percent combos
OK, I'm back with a pretty awesome down throw combo from 0%.
Down throw > weak nair > weak nair > regrab > down throw > weak nair > strong nair
If this gets them offstage, go for a dair spike. If not, space them out with fair, then start setting up your next attack.
