Episode 5 Face Hunter
Pretty simple mulligan here, never keep any secrets in the opening hand or Leeroy/Arcane Golems. You are looking for Mad Scientists or any 1 mana drops. If going second, it may be OK to keep a 3 drop, especially the Bow to deal with Mechwarpers or Northshire Clerics. Double 1 drops on turn 1 with the coin is also good if you have a turn 2 play.
