Also I respect the opinion of @ELEX and his constructiveness very much; however I disagree with many points brought up here:
-Maintaining the "nature of a synth" in my view means: no effects. I'd be ok with that, could be a fun challenge. But please not every round!
-Phasing and filter modulation is not the same thing at all
-External effects are not only used for cleaning/polishing in OSC, but very often for pure sound design. Just throwing OTT and Valhalla Super Massive in the ring
-sure you can substitute internal effects with external ones, as long as they're not forbidden, why not? You don't need to use the e.g. terrible reverb of a synth, just grab a better (allowed) one
-What's "modulation" really? I'd agree when talking about oscillator driven modulation entering audible frequencies. Manually designed automation is a much tamer beast.
Of course I lay the destiny of my very controversial creation trustfully into the hands of the organizers.
Take care everybody and keep it fun!
