Caw Gates is a grindy midrange deck full of small efficient creatures like Sacred Cat, Outlaw Medic, and Sneaky Snacker backed by Journey to Nowhere and Prismatic Strands to protect its board. Tragic Slip is excellent removal here since a creature dying is common in the mirror of attrition, letting it two-for-one their small bodies for one mana. Spinning Darkness gives us reach and life gain against their lifelink and go-wide plan, dealing with a nonblack threat while offsetting Sacred Cat's or Outlaw Medic's lifegain. Unearth and one Rite of Consumption come out since we want efficient removal over recursion against a deck that out-grinds slower plans.
