Cursing is the cheaper alternative, but since you are using multiple curses at once it is almost triple the XP. I don't know all the curses off by heart but there are about 3 of them. Just do what I said and see what happens, when I was leveling I was clicking every few seconds to get more goblins against the fence.
Im not too sure what the xp per hour is, but it is probably good at that level.
Plus it will be much cheaper than teleports.
