These are really good questions . 1 . I was on the fence about Whispers of the Muse and almost cut it for the 4 th Think Twice before the tournament . It does give nice inevitability but you have so much other buyback , and it ' s a bad card to draw early . I ended up deciding just to cycle it if I drew it early and that worked out for me , but I could see it either way . 2 . I ruled out Accumulated Knowledge on theorycraft a . k . a . I didn ' t test it for two reasons . First , I didn ' t want my deck to be too dependent on having a live graveyard in postboard games . If my opponent brings in graveyard hate , it ' s not hard to play around it with Think Twice , because it only takes 5 mana to cast it and immediately flash it back . The opponent is typically pressuring me less because they drew and cast a hate card . Second , I felt that running AK would worsen my close UB Delver matchup because they use AK far better than I do . 3 . I did test with Havenwood Wurm and consistently didn ' t like it . Even the Sea Gate Oracles turn on opposing removal to an extent , but at least they draw a card in the exchange . Drawing Havenwood Wurm naturally was miserable . A large flash flyer has the same problems , but I would have considered playing one if there were a 4 toughness option so that it could trade favorably with Delver . Unfortunately , that doesn ' t exist . 4 . The main targets on the opposing end are Myr Enforcer and out of Affinity . Remember you can target your own artifacts as well , though ! In a deck that typically dips to low life before stabilizing , it is tutorable life gain when I need gain 4 life now . I have cast it on Expedition or Pristine Talisman more than once because I needed the life right then . For what it ' s worth , I have yet to play a game where I cared about my opponent ' s life total . 5 . Innocent Blood is a reasonable consideration that just didn ' t make the cut . I felt I had enough edict effects , and it doesn ' t play well with Sea Gate Oracle . It ' s not bad , though .
