Dimir Tempo plays colorless artifacts like Mishra's Bauble, and Orcish Bowmasters triggers can hurt us, so Consign to Memory can counter those cheaply by hitting either the colorless spell or the triggered ability; it's a solid flexible answer in this countermagic mirror. Barrowgoyf gives us a resilient deathtouch/lifelink body that outgrows and out-blocks their Nethergoyf in a grindy game, since it counts card types in all graveyards while Nethergoyf only counts their own. Cabal Therapy loses value since they dump their hand quickly via cantrips, and Wail of the Forgotten is too slow and card-disadvantageous against their efficient disruption plan. We keep our full Force of Will and Daze suite since protecting our own threats is critical in this matchup.
