I get the point that you wanna build up your collection to be able to pick from the best models available, but how about you try and play / learn the models you have first, before you add more stuff you don't know how to play in various situations? Just bc I now tell you to buy the Emissary (okay dang, the Emissary is probably a bad example :P) doesn't necessarily mean you need it / it suits your play style. I don't mean it offensively in any way, just as an advice You already have a pretty good collection which will keep you busy for quite some time.
