Most of the creature types were focused on two colors, so it gave us the opportunity for a theme
Edit: Nevermind
Blue is the color that has access to the most cards that can draw for no cost, and when mixed with red, which has plenty of ones that draw and discard cards, you have a fantastic archetype to play with
Livindavido knows about it because I told him about it because I read KEIs thread two years ago, which is the only sufficient English documentation on this card across the entire internet
Red only cares about power, and this effect is awesome when you combine it with abilities like double strike or fling effects
