mtg cards by price of Knowledge - Commander 2013 Destroy target creature Price of Knowledge
Description
The fact you might be able to determine the presence of a high-value card before you've even cracked a pack is pretty interesting

You can attack with a Kaalia on turn four or five, and then drop an Akroma, Angel of Wrath or an Ancient Copper Dragon to attack alongside her

If your resolve matches Wrenn's, then a little impulse won't hurt from time to time

But as pure card draw effects go, this Font is one of the most efficient and straightforward
