This is my Rat Farm deck, which features a few humans that tend to the rats/lead them to wipe out my opponents. This is a fun Rat Vorthos deck, with most of the deck running weird cards. Diligent Farmhand is ramp, and Muscle Burst can end a game quicker, something I like to do, and helps deal with situations where I only have 1 or 2 rats out, and am vulnerable. Harmonize isn't the strongest draw option, but I feel like it's on flavor for the deck, the humans living a harmonious commune with the rats, leading them to victory. The deck is desperate for removal, but I'm not sure of good Vorthos removal, atm we can steal something late game in a pinch, but we're actively bad at removing stuff pre-board. I think we still suck at removal after because we leaned into Green removal, the sideboard is probably not doing what I need atm so we'll see.
Should I just ditch the slower rats and go for full speed instead? One idea might be to switch in some Sewer Rats, which are able to squeeze for a lot of life potentially, when you've got nothing else to do with the mana/life. They're not good, but I think they're solidly better than any other 1 drop Rat.
Should I toss in a Karumonix, the Rat King or 2? I feel like I'd want a few more rats to really make that card go, but atm it's ~1.8 rats in 5 cards, which is far from bad. I'm wondering about x1 Marrow-Gnawer, x1 Ogre Slumlord and x2 Karumonix, but maybe I just want to use Marrow-Gnawer somewhere else, rather than it being bad here?
