Abzan Greasefang wants to assemble Esika's Chariot and Parhelion II (via Greasefang, Okiba Boss reanimation) as their key noncreature permanents, and Reclamation Sage answers both outright before they generate value. Skyreaping is weak here since their only real flyers come from Parhelion II's token-making triggers and it requires devotion to green to matter, so only bring minimal copies as a sideboard trim if you expect those Angel tokens to matter; otherwise favor Reclamation Sage. Cut small, removal-vulnerable bodies like Badgermole Cub and some Vastlands Scavenger copies since this matchup is about denying their engine pieces rather than racing with small creatures. Focus your plan on killing Esika's Chariot and Parhelion II before they crew and attack.
