We present multi-wavelength temporal and spectral characteristics of amagnetic cataclysmic variable (MCV) Swift J0503.7-2819, using far ultraviolet(FUV) and X-ray data from AstroSat, supplemented with optical data from theSouthern African Large Telescope and X-ray data from the XMM-Newton and Swiftobservatories. The X-ray modulations at 4897.6657 s and 3932.0355 s areinterpreted as the orbital ($P_{\Omega}$) and spin ($P_{\omega}$) period,respectively, and are consistent with prior reports. With a spin-orbit periodratio of 0.8 and $P_{\Omega}$ falling below the period gap (2-3 hrs) of CVs,Swift J0503.7-2819 would be the newest addition to the growing population ofnearly synchronous MCVs, which we call EX Hya-like systems. Hard X-rayluminosity of $<$ $2.5\times10^{32} erg s^{-1}$, as measured with the SwiftBurst Alert Telescope, identifies it to be a low-luminosity intermediate polar,similar to other EX Hya-like systems. The phenomenology of the light curves andthe spectral characteristics rule out a purely disc-fed/stream-fed model andinstead reveal the presence of complex accretion structures around the whitedwarf. We propose a ring-like accretion flow, akin to EX Hya, using periodratio, stability arguments, and observational features. An attempt is made todifferentiate between the asynchronous polar/nearly-synchronous intermediatepolar nature of Swift J0503.7-2819. Further, we note that with the advent ofsensitive surveys, a growing population of MCVs that exhibit characteristics ofboth polars and intermediate polars is beginning to be identified, likelyforming a genealogical link between the two conventional classes of MCVs.
