Gruul Sligh is an aggressive red-green deck that aims to kill you with a swarm of creatures and burn spells before you can execute your reanimation plan. Snuff Out provides free interaction that doesn't disrupt your combo setup, cleanly answering threats like Grim Lavamancer, Jackal Pup, and Quirion Dryad. Sickening Dreams serves as a sweeper that can clear their board when you're holding multiple dead cards (like extra reanimation targets), turning hand size into a board wipe. Multani, Maro-Sorcerer and the extra Phantom Nishohas come out because the match is largely decided on speed — you want to reanimate Akroma or Verdant Force as early as possible to stabilize, and the slower or more conditional threats are less important here.
