United in Stormwind Cards List & Guide
Total Deck Rating
There is no way to reduce the cost of Mecha’thun or Bloodbloom. My guess is that you forgot to include an Emperor Thaurissan or something.
After some thinking, I have decided to remove the Abyssal Summoner for Thaurissan instead. If you can think of a better replacement instead, please tell us.
You're right! Thanks for reminding me.
