Instead of that, i would just remove the limit of 9 per draw, so that if your magic power was strong enough, you could draw, say, 20 in one turn. Besides, it's hardly a problem anyway. You can easily and rapidly acquire lots of different magic through GF menu commands.

I have no problem what so ever with monsters levelling up with you. You only need to get your focus away from trying to gather as much exp as possible, and more towards efficient junction setups, because that's how you really get strong.
