Also you need to have a premium membership to use eggs; but a basic you can get straws

If you buy embryos, you need a surrogate to turn that into a foal. And if you have a premium upgrade and can flush eggs and create your own embryos, then you can use surrogate mares to create several foals from the same dam in a single season. Otherwise there's no real reason to use surrogates. They don't allow you to produce better foals than you could by implanting a straw in a mare directly and having her have her own foal. Using the straw to create an embryo from the mare and then implanting that in a surrogate allows you to breed the same mare more than once without using eggs, but I'm not sure how many times. And it costs more than creating an embryo with an egg and a lot more than just using a straw directly.

Okay that makes a lot of sense! Thank you for the explanation. :)
