A good Dragon type.
Most dragons can learn Earthquake, and are also of the Flying type... so there goes your Fire Pokemon. Water moves aren't very effective on Dragons, and Dragons sometimes can learn good Grass moves. Earthquake would already put your Danphan in a world of hurt because of his Electric type, and Ludicolo could be easily taken out by a Flying move (often compatable with Dragons), leaving one poke that could pose a bit of a threat.
The most I would fear with a Dragon against that team is a strong Ice Beam, or Blizzard, as most water types can learn both. But the fire portion would easily be owned by a Dragon who knows Earthquake (and thus making your Earthquake useless, with the common Flying type in Dragons).
Not a bad pick, though. Just watch out for Dragon types. ;-)
Earthquake doesn't do crap against a proper Donphan (It isn't Electric, btw, it's Ground) due to its high defense and every water type can learn an Ice move so there goes the Dragon (As most of them have a double Ice weak). Also, the only Grass type moves that any dragons can learn (Excluding the 4th gen) are Hidden Power [Grass] and Solarbeam, neither being any good for them. :O This is not to say that lineup doesn't have serious flaws, however.

Just Think of a Pokemon that could defeat me......
A STAB water attack or two takes care of four pokes on the team (Camerupt, Donphan, Charizard, and Magcargo) and a few good electric hits gg Blastoise. Basically, five out of six pokes on that team fall easily to Starmie, which would kind of leave Ludi hard-pressed. Heracross would probably put it out of its misery with one Megahorn. So no, that's not really my idea of unbeatable.
Anyways, I agree that single-type gyms aren't going to cut it (And besides, they're rather boring) so I'd go for a thematic one instead: ancient pokémon. =D The only downside I can see is that I'd probably end up with a bunch of ruin maniacs hunting ancient relics all over the place and making a royal mess. <.<
Still, that would give me access to lots of cool pokémon, so I'd have a team of something like...
Aerodactyl
Omastar
Cradily
Lapras
Relicanth
Armaldo
Of course I could also interchange with pokémon like Claydol and Kabutops so as to not make it so monotonous. If D/P pokémon were added to the mix I could also get a better type coverage, but I guess this team could (Sort of) pull through even without it. Besides, all of them are pokes I like. *Hugs Cradily*
The gym itself would probably be in one of the average-sized cities, not some lousy one-Miltank town without running water but not a huge, bustling metropolis either (Those give me a headache). Preferably somewhere by the sea-side as well since that's the kind of environment I'm used to (Not to mention that most of these pokémon are sea-dwellers). On the inside, the gym itself would more or less consist of just the battle arena, a simple, straightforward one, 'cept maybe with some homey little touches like Ruins of Alphesque runes on the walls (Could be used to spell out a gym motto or just really random things) and maybe some cheap replicas of old carvings depicting pokémon. In conjuncture to this room there would be one darkened and damp one for some of the pokémon (E.g. Cradily, Omastar, and Relicanth) to rest up in and another one for my personal use.
The gym would, in turn, be in connection with a thematically related facility like a museum or antique shop, and on the outside there would be no direct indication of it even being a gym, so only those smart enough to discover it would get to challenge me (That should cut down the amount of worthless challenges by a good bit ^^).
And that's it, props to Toomi and anyone I didn't notice for going with favourites rather than just power. ^^
