Lands is a grindy prison deck that wants to assemble Dark Depths/Thespian's Stage or lock us out with The Tabernacle at Pendrell Vale and Wasteland, but it has very few actual creatures, making Cabal Therapy and its flashback (which requires sacrificing a creature) awkward since we may not want to sac our own reanimated threats just to strip a card. Snuff Out is a marginal bring-in here: it can only target nonblack creatures, so it cannot touch Marit Lage (a black Avatar) at all. Its realistic targets are Icetill Explorer and the colorless Construct tokens from Urza's Saga, which it can kill for free by paying 4 life while we control a Swamp. Our best angle is still resolving Griselbrand or Atraxa quickly to get ahead on cards and life against a long grindy prison plan, and Unmask/Thoughtseize remain useful to strip a key nonland piece like Grafdigger's Cage, Disruptor Flute, or Pithing Needle before it shuts off our reanimation plan. Neither can take a land, so Wasteland and the other lands will stay in their hand.
