If you manage to get Emperor Thaurissan to reduce the cost of Malygos and at least one spell, you get huuuge damage. Mind Blast does 10 damage, costs 1 mana. Without Malygos, Velen is your only way to nuke the opponent. If you're playing Warrior, even Velen+2x Mind Blast won't kill em. You need something else to get enough damage, and Maly is it.
