Bleed Them Dry: You start with ZERO mana crystals and never gain any. Cards that would generate mana or mana crystals do nothing. Instead of paying mana, you pay life to play spells and use hero powers. Starting life total - 40
King of the Mountain: For each 10 brawl games you win, your starting life total is increased by 10 health, minions you control get +1/+1, and spells you play cost 1 less.
Shady Dealings: Constructed. Before the brawl begins, you have a 50% chance to swap decks with your opponent. Do you build a terrible one and hope to give it away? Or a powerful one and hope they don't steal it?
