Saga Storm vs Eldrazi

Eldrazi's Chalice of the Void on X=0 or X=1 is devastating against our mana-cost-0 artifacts and cheap rituals, so we want to minimize our own vulnerability window; Tormod's Crypt is a free artifact that doesn't tax our mana but can proactively exile our own graveyard before an opposing Kozilek's Command mills/exiles it, and more importantly denies any graveyard value they generate. Grafdigger's Cage is mostly a sideboard safety valve here but costs little. We trim Mishra's Bauble and a Cabal Ritual slightly since both are cost-0/low-value against a deck not relying on card quality to out-grind us, favoring resilience to Chalice of the Void instead.
