Strategy Explanation: Get Douse into play. Then use Sleight of Mind to change it to what ever color your opponent is using, if the deck is multi-colored then choose the color that best suits your match. Then get Arcane Laboratory into play. Since they can only cast one spell, you can counter that spell. You will have a lot of spare mana to use so Chimeric Mass can be a good beater plus you have the Celestial Colonnade to beat them down.
