A full MF game for me consists of...
Countess, Andy, Ancient Tunnels, Summoner, Lower Kurast, Trav, Meph, Shenk/Eldricht, Pindle. If I'm feeling feisty or have extra time to goof around I might add in the Mausoleum, River of Flame and maybe Chaos Sactuary, and possibly WSK-Ball depending on what spawns in the game I'm in. Sometimes I'll also open Cows, kill everyone but the king and then bring my lightning trapper in just for the king kill.
I'm running a Blizz/FB sorc using Tal's set minus the orb (have to find it yet), rare +2, 20%FCR, resists orb, rare rings with resists/mana/FCR/life/MF, Lidless Wall-pDiamond, a 156/40/13 Gheeds (Thank you, Andy!!!), Magefists, Silkweaves. Skull Collecter on switch for boss kills. Soon as I get around to it, sockets will go in the armor, helm and Skull Collector, which will be filled with pTopaz (armor and helm) and my hellforge Ist in the staff. I'm holding off on the staff since I found a Ali Baba, if I can get another Ist I'll dual-ist that and put it on switch with my Rhyme luna instead of using the Skull Collector.
Merc is act 2 Defiance with a Leviathan, Tal's helm and Insight Cryptic Axe.
I like doing long run games like that instea dof fast single boss runs. It's more entertaining, less monotonous and no chance of temp ban for making games to fast!
