Minimal Colossal is one of my favorite approaches from the neoclassic Kolossal Killer from Kenton Knepper.
- One envelope in full view
 - Any playing card is named through a simple and flowing procedure
 - One card, completely correct
 
In this video you will learn the basic secrets, a simple and effective use of the classic OBO principle (thanks Kenton for your permission and blessing), the construction of the special envelope (DIY, very simple to make) and much more. You will learn variations and extra uses and ideas using the methods at play.
- 100% practical for all situations
 - No bulky wallets, nothing to fail
 
If you are interested in a direct, powerful and simple way to predict any playing card, Minimal Colossal is for you.
