That's more an issue with the design of your deck than with the game, or the design issue is that one may not know how to build a deck to avoid such issues. MTG isn't built for a consistent (late) game natural Mana curve and being able to do what you suggest would fundamentally change the game. For worse imo. For example with no Mana acceralation/mananipulation the optimal number distribution to have to maximize Mana spent through turn 5 is 29 lands and only 3 five drops. After which you will quickly have more Mana than you need. Very few decks run 30 lands. You can't design a deck that satisfies the condition of natural ly dropping a land each turn and spending the most Mana. The more consistently you want to say, have 5 lands on turn 5, the more lands you need, which means less space for other cards in your deck. Similarly the more you want to be able to spend that 5 Mana past turn 5 the more higher cost cards you need, which means fewer cards of other cost. Which means your more likely to be Mana flooded early since your deck won't have the space to consistently play smaller stuff. Try to and will come at the cost of making it more difficult to curve at higher N. The optimal turn 5 deck curve has no 1 drops. You can't have it both ways. As for your suggestion, it would only be better for beginners who don't know how to build around a curve, as the cards are not designed for such rules and would break the game in other ways.
