Ichorid I side out Eternal Witness, Vendilion Clique, Trygon Predator, two Swords to Plowshares and one Qasali Pridemage for two Faerie Macabres, two Relics of Progenitus, and two Path to Exile. If I'm running Dueling Grounds/Ghostly Prison I'll board those in too.
For Merfolk I board in three Umezawa's Jitte/Dueling Grounds, two Path to Exile, and Kira, Great Glass Spinner for Eternal Witness, Meddling Mage, Vendilion Clique, Trygon Predator, Qasali Pridemage, and Noble Hierarch. If they aren't running Stifle I might board out another Noble Hierarch or two.
I'm not too experienced in the Merfolk matchup, so I might have that wrong. You could also board out Meddling Mages against Ichorid for extra Paths to Exile.
