Azur Lane's German roster is running beyond completed warships

Which German ships would be good choices for Azur Lane's June mini-event?

Schlesien, Schleswig-Holstein, or the 1925 Emden would use real ships before the game goes still deeper into paper designs.

Azur Lane's Iron Blood faction mixes real German ships with paper designs and looser inventions. The old battleships Schlesien or Schleswig-Holstein and the 1925 cruiser Emden were real ships still available for adaptation. Their completed service distinguishes them from documented but unbuilt designs and characters invented to keep the faction supplied. The suggested event choices would therefore broaden the roster through historical ships that actually served.
