I know Zwei has a focus on size 3 style, but when I look at these demonic retainer, it didn't feel they are made to be size 3 focus. Of course you could play Ewigkeit to play them, but you have no searcher for him and other size 3 Zwei monsters and if you add the size 3 monster spell but no way to have a size 3 on your field, you're in bad shape.

This deck style (as result of test) seem to be able to fastly call a 2 or 3 formation. If it could have a transform with it, it could be helpful.

For Dark Sun and Rain, they are good ideas ^^
