The Velen Majordomo Dream
Yes I do play Hearthstone but I've never wanted to make a habit of uploading anything that isn't out of the ordinary and awesome. This definitely falls under that category.
The original plan was for me to trigger Ragnaros using my own Big Game Hunter on Majordomo Executus, but things worked out well in the end anyway. Also I actually could have pulled it off 1 turn sooner if I'd paid better attention.
Important Cards used:
-Prophet Velen
-Majordomo Executus
-Emperor Thaurissan (decreases cost of cards by 1, needed for Velen and Big Game Hunter)
-Big Game Hunter
-Mind Blast (If Majordomo gets triggered by trading or getting removed)
