Unlike with many previously Monthly Poké Fair Scouts, Marnie & Morpeko do not appear to have received new fair-exclusive tiles in their sync grid in conjunction with this scout.
As normal for Poké Fair Scouts, 5★ sync pairs have a 10% chance of appearing in this scout. The first five times players perform a Sync Pair Scout x11 for the Monthly Poké Fair Scout Vol. 10, they will also receive a bonus present of 3★ Friend Key x15. These keys allow players to increase the Friendship Level Cap for a single Guest in the Trainer Lodge by 10. This Monthly Poké Fair Scout also includes a daily discount, where players can perform a single scout for x100 paid gems. This daily discount can be used 1 time per day during the entire length of the scout.
