I'd say, try to rewrite the ability as you would do without knowing about
Mire's Toll. It could help.
In the meanwhile, look at what I made...

I just tested it with
Shock, it would need a much more extensive testing before calling it right, anyway, I'll leave the tests to those who need the card.
EDIT: Version 2 fires the BECAME_TARGET triggers for each creature the copied spells are about to target (the copies don't do that by themselves). It's still not perfect, though, because the FireTrigger function accepts only 2 parameters so I can't set the SecondaryObject (and to be honest I wouldn't know how to get a pointer to the spell copy after creating it). This means, for example, that
Ashenmoor Liege will never trigger off a spell copy from the Nephilim.
