Five life is quite a lot to pay in todays Commander metagame, but this feels costed just right as something that will cost life on crucial or early turns and otherwise just cost three mana

There are some Slivers still available to players on a budget, as well as some Sliver-centric spells that can kick Sliver Swarm up a notch

its making them pay for all the land they have

For that reason I think Niambi is fine as a commander but better in a deck that has access to Black, such as Sisay, Weatherlight Captain

Even if I've convinced you that incarnate is a good thing when designed well, I still need to defend lack-of-variance
