Foil Ajani, Mentor or heroes and Voice of Resurgence

Hey guys I have decently valued foil cards, listed in the title and I'm looking to unload them for some modern staples since I'd like to get into the format. The main cards I'm looking for at the moment are snapcaster mages and scalding tarns. I know that My foils don't equal the price of a fetch land but I have other things that I'd be willing to throw in to make up the difference
