As for Phoenix Slayer Magic and Spirit Slayer Magic, they were made before logical rules were integrated during the site's early years. Now, it's much better so there's not over 4000 billion forms of Slayer Magic which makes no sense at all. The reason the Phoenix and Spirit Slayer Magics predate this rule (but I do get what you mean with Spirit Slayer, as for phoenixes, yeah idk about that either).

However, like Oraclehistore75 stated, giants can be defeated with a powerful form of magic (although, was basically instantly defeated by Natsu with Dragon Slayer Magic XD). Even so, Slayer Magic is a lost, rare magic, and since no such Slayer Magic comes into the manga, it can't be made. But for Phoenix and Spirit Slayer Magics, that I do understand since I also questioned their existence (was told it predated the rule and that's it).
