Last updated on Dec 10, 2019 at 18:00 by Kat 1 comment

This guide contains detailed Strategy, Mulligan, and deck-building information to help you play Big Spell Mage in Descent of Dragons expansion.

Big Spell Mage is an archetype that only uses a very small amount of cheap spells and minions in favor of using a specific subset of expensive cards that synergise together to create powerful plays, starting in the mid game.

Big Spell Mage has been revived by the Savior of Uldum expansion, gaining access to the Puzzle Box of Yogg-Saron card and many spell synergy cards like Naga Sand Witch and Tortollan Pilgrim.

Big Spell Mage Mulligan Guide

Big Spell Mage is a slow deck that does not hit its stride until at least Turn 5. To account for this, you should use your mulligan to find any cheap cards to help survive the early game.

Big Spell Mage Strategy

The aim of Big Spell Mage is to survive the early game by any means necessary. After reaching Turn 7, your aim should shift to playing Luna's Pocket Galaxy to discount minions in your deck and, if you have powerful spells like Pyroblast and Puzzle Box of Yogg-Saron in hand, using Naga Sand Witch to discount them.

With your card discounts active, you can begin to start taking the fight to your opponent. The inherent variance of the deck means that no two games will be the same and you should think carefully about your turns. However, as a general rule, you should try to maximise the value from Blizzard and Flamestrike to control the board, while trying to pressure your opponent with your minions. If at any point your opponent has minions in play and you do not, Puzzle Box of Yogg-Saron is also a solid option. While the card may be very random, it will generally kill most minions on the board, while spawning you a couple of minions and drawing a couple of cards.

While the spell-support minions of the deck can put good pressure onto opponents, most games should come to an end when you are able to use Pyroblast directly on your opponent, reducing their health with Alexstrasza beforehand if necessary.

Against Aggro, you should put a lot of emphasis on clearing the board, using Tortollan Pilgrim to cast additional copies of Flamestrike and Blizzard if necessary. If you are able to get into a position that you can safely develop minions, you should be able to comfortably cruise to victory against Aggro.

Against Control, you will need to maximise the value of your cards to ensure you can win through a long game. Using Tortollan Pilgrim to cast additional copies of Puzzle Box of Yogg-Saron when your board is empty will greatly help with this. It is also a good idea to hold onto both copies of Pyroblast, after they have been discounted to 5 Mana, so that you can quickly burst down your control opponent before they are able to heal back up.
