Caw Gates leans on small creatures like Sacred Cat and Eldrazi Spawn tokens from Malevolent Rumble, so Krark-Clan Shaman gives us a repeatable way to sweep their 1-toughness threats by sacrificing our own artifacts. Kenku Artificer is a fine card generally but is a slower, more clunky play against a deck that wants to grind out incremental value with lifelink and Prismatic Strands, so we trim it slightly for a cleaner curve. Keep our removal suite intact since Journey to Nowhere and Prismatic Strands mean we need efficient ways to punch through blockers and answer their threats. This matchup comes down to who develops their board faster before Prismatic Strands can blank an alpha strike.
