Most likely SU UMa star from ZTF data (superoutburst +
rebrightening in 2020 Sep.-Oct.).

Re: DDE 35: more likely a polar
E. Pavlenko has advised that this object is too blue
for a polar. The data by Crimean Astrophys. Obs. team
in 2020 showed flickering, but no indication of
stable superhumps nor orbital variation.
Although a period of 0.20976(3) d was suspected from CrAO
observations (by my analysis), this period was not
detected in the ZTF data.
This object indeed looks like a CV with high/low
states, but is certainly neither an SU UMa nor a polar.
This object is currently in high state and would be
an easy target for spectroscopy to determine
the orbital period.
