I disagree, this locks red into extremely redundant linear strategies where every card is trying to do the same thing. That's pretty boring deck design. Red should certainly be more than just burn and agressive creatures for example.

Unless the 4 decks instead of 4 allow for a rearranging of the printing sheets... Then may be.
