  We report on Chandra, NuSTAR, and MDM observations of two INTEGRAL sources,
namely IGR J17528-2022 and IGR J20063+3641. IGR J17528-2022 is an unidentified
INTEGRAL source, while IGR J20063+3641 was recently identified as a magnetic
cataclysmic variable (mCV) by Halpern et al. (2018). The Chandra observation of
IGR J17528-2022 has allowed us to locate the optical counterpart to the source
and to obtain its optical spectrum, which shows a strong H$\alpha$ emission
line. The optical spectrum and flickering observed in the optical time-series
photometry in combination with the X-ray spectrum, which is well fit by an
absorbed partially covered thermal bremsstrahlung model, suggests that this
source is a strong mCV candidate. The X-ray observations of IGR J20063+3641
reveal a clear modulation with a period of 172.46$\pm0.01$ s, which we
attribute to the white dwarf spin period. Additional MDM spectroscopy of the
source has also allowed for a clear determination of the orbital period at
0.731$\pm0.015$ d. The X-ray spectrum of this source is also well fit by an
absorbed partially covered thermal bremsstrahlung model. The X-ray spectrum,
spin periodicity, and orbital periodicity allow this source to be further
classified as an intermediate polar.
