I'm not a fan of sprites as snapcasters have taken over it's slots. So without sprites, what are the best colourless lands/karakas? I think it's a fight between mishra's factory, moorland haunt and karakas.

I was running 4 factories and they're great with soff. You can bash with an equipped factory out of nowhere and untap all your lands. They always have to play around that when it's on the table. Just picked up a moorland haunt, so I'll give it a try. I think 1 is the max I'd run, since we don't have that many creatures.

Factories seem best because they are even better in multiples.
