We present low-resolution phase-resolved spectra of the polar MT Dra during its high states in 2006 and 2009. Balmer series, He I and He II 4686 \AA\ emission lines have complex shapes and show similar profile variations over an orbital cycle. The radial velocities vary with orbital period and display motions of the gas falling close to the magnetic poles of the white dwarf.
