It's a very annoying problem and must be solved once and for all. It's a question of lucky and bad lucky than skills when you just draw nonland permanents you don't need or when you just draw lands when you most need nonland permanents. That's far from a fair play and it must be fixed. We should have 2 libraries, one library based on lands and the other based on nonlands permanents. Each time you start your turn you choose which of the 2 libraries you want to draw. No one will never complain about drawing only lands or nonland permanents. The game would be quite balanced and finally fair than ever. The duels would be fair and much more exciting. It's too simple to end for all this problem with a system like this implemented to fix this annoying problem.
