WU is packed with Force of Will, Daze, and Stifle to counter or fizzle our reanimation spells, so Chain of Smog is huge here — it strips two cards from their hand for one black mana, often taking their only counterspell and a follow-up answer in the same cast, and dodges Stifle since it isn't targeted at a permanent. Borborygmos comes out because it's a clunky mana sink against a deck that will just Swords or bounce it, and one Raph & Mikey is cut since Wasteland-heavy decks punish our nonbasic-light manabase less but the legend still competes for graveyard resources. Keep leaning on Thoughtseize and Cabal Therapy pre-combat to clear a window, then jam Reanimate or Animate Dead on Griselbrand to refill and close. Watch for Karakas bouncing your reanimated legendary creatures — sequence Atraxa or Raph & Mikey around open Karakas mana when possible.
