Sore wa Dou Kana

A phrase that you say while playing card games say when your opponent gets cocky and feel like he/she would win, not realizing the fact that you have either 200 IQ or heart of the cards on your side and eventually wins the game.

Enemy: "I have a straight flush in my hand, i definitely won the game"
You: "Sore wa Dou Kana" *reveals royal flush in your hand*
