On the special side we have Exeggutor with Sleep Powder, Psychic STAB, fair bulk and a lot of SAtk for a NU mon.
On the physical side there is Leavanny with Bug STAB and Swords Dance; Sawsbuck with Normal STAB, best speed disregarding Jumpluff, a plethora of coverage options Swords Dance; Leafeon at least has fair bulk and some odd moves like Wish.
Shiftry makes both a good special sweeper and a physical sweeper, for it has Swords Dance and Nasty Plot and strong Grass and Dark STAB moves on both side.
I was tempted to suggest you using a Spike set with Maractus but soon realized that that way we turn back to Cacturne who has Spikes, too, and more. Really, Maractus is outclassed in basicly everything it is trying to accomplish.
Edit: In hindsight I would have told you to use it as a Sun-Spiker, as it is the only Mon with Chlorophyll and Spike. As expected there already has been an analysis on Smogon.
At least this kind of set is unique, albeit it still sucks.
