My suggestions: - 2 mana princess "Battlecry: If your deck has only 2-cost cards, deal 10 damage to both heroes." because obviously you must play super aggressive with a 2-cost deck before you run out of steam.

• 3 mana princess "Battlecry: Discover a minion in your deck and summon 3 3/3 copies of it." because 3-cost deck is really slow and you need some huge tempo boost to even stay in the game.

-4 mana princess "Battlecry: If your deck has only 4-cost cards, your minions have Lifesteal this game." because again, this deck is super duper slow. You will probably at 10 health by turn 4 vs zoo, and you can't really pressure control decks until turn 8.
