Ursarctic mixed with atlanteans just because it works (not due to common water attribute either). Basically you can do any other engine but atlantean just had so much plus to it.
Deep sea Diva + Deep sea Aria + Ursarctic departure landed me with Auroradon, Dragite, borreload savage dragon, crystal wing and septentrion with a moulinglacia hand rip.
End note, ursarctic can be an engine now for a lot of decks kind of like dogmatika. Try it in anything.
