Consign to Memory is a colorless-spell/triggered-ability counter, so it stops Orcish Bowmasters' enters-the-battlefield and draw-punisher triggers as well as colorless spells, which is valuable against their value-token engine. This matchup is mostly a race where we want to resolve Show and Tell or Omniscience before they overwhelm us with Cats, so we trim slower, non-essential cards rather than core combo pieces. Veil of Summer is tempting but their deck is mono-white with minimal blue/black spells to punish, so it stays in the sideboard. Keep pressure on resolving a fast Atraxa or Emrakul since their removal (Swords to Plowshares) is the main answer to our win conditions.
