In 3.5 is difficult to abuse Haste, but a Fly core caster/escapist would be all except original (I saw one at my very first d&d game, so...). Moreover, if someone does it, I suppose it will hit even a poorer score in originality: since as a spellcaster you have millions of options, one would be less indulgent if you did something so uninventive.
As a suggestion to anybody: links to previous competitions are not there to let you see how cool usual competitors are, but to get inspiration and an overall look on how something is judged (overall: be warned that any judge has his own taste and the right to have it ).
