Note: This deck is NOT a competitive deck. DO NOT play it on ladder.
The main purpose pf playing this deck is to make the following combo when Majordomo Executus is on board:
Steady Shot + Feign Death + DIE, INSECT! + Feign Death + DIE, INSECT! + Majordomo Executus goes face = 27 damage.
This can deal more damage if you have equipped Eaglehorn Bow : triggering Majordomo Executus's deathrattle refreshes your hero and you can attack several times in one turn with your weapon.
Sometimes you can also use Big Game Hunter to trigger Majordomo Executus's deathrattle to deal more damage if you don't have enough Feign Death to do that.
All these combos can be played with Emperor Thaurissan in order to use DIE, INSECT! as many times as possible in one turn.
Even though Feign Death is one of the most important cards in the combo, you can also use it in other ways (especially when facing midrange decks) to survive until you draw Majordomo Executus. For example, I've won many games with the Feign Death + Sylvanas Windrunner combo against combo druid and midrange hunter.
VS aggro: Explosive Trap, Powershot, Dreadscale, Quick Shot and Antique Healbot(if you have enough removals)
VS midrange: Loot Hoarder, King's Elekk, Eaglehorn Bow, Animal Companion, Deadly Shot
Even though this is a combo deck that relies on Feign Death, don't ever try to keep Feign Death at the opening hand. What you need is board control before you can use your combo.
