What is the most efficient way of training magic? I have been cursing dummies in Lumby but I get around 30k exp/hr and it's really boring and slow.

 

What should I be alching to lose the least amount of gold? Is there another fast method to training magic other than alch?

Fastest I'm not really sure about but I personally love superglass make as it also nets a decent amount of cash along with a decent amount of crafting xp which will help when you hit level 80 and can use string amulet which is very fast and also very expensive. Also bursting rock lobsters for crimson charms is an option but is once again highly expensive but good if you need the charms to train summoning. Also about your comment about alching to my knowledge there is no item that you can purchase on the grand exchange along with nature runes that can make a profit. That being said there are some items such as yew longbows that if you cut the logs and buy the strings and the nature runes you can fletch the bows and then alch them for a profit but it requires cutting the logs and fletching the bows though. (also nets some nice fletching xp, I use this regularly)

Granted this was back like 2 years ago....

 

Enchanting in the Magic Training Arena is very good experience/hr. If I remember correctly back when muggiwhplar and myself were going for 99 magic...That was a very good and cheap way to do it with Cosmics being cheap. Granted I PC'ed my Magic levels from like...98-99. Goodluck.
