I am sure after some shoddy battles I can come up with something wrong with a type of pokemon....and make a useful concept...heh, seriously guys, stop with the multiple spur-of-the-moment ideas. Take some time, think it out and put 3/4 of your best ideas into one post, people will take your ideas more seriously and it's much easier to keep track of things.
I don't see any huge benefit in a lot of speed on a Pokemon with extremely high defenses. It just costs him a lot of efficiency, and makes his offense shit. For hardly any benefit. Speed only matters if either party is about to die. This thing will never kill its opponent (especially not with Rapid Spin), nor will it die anytime soon, so most of the time its high Speed is wasted. Rapid Spin should hardly ever occur on a turn said Pokemon is about to die anyway.
It just doesn't seem like a useful concept.
Concepts should be presented as high-level descriptions of a general idea. They should not be detailed pokemon designs. Since we have polls to determine each aspect of the pokemon, we don't want the entire pokemon determined by the details of the Concept.
EDIT: Type combos and Typing ideas are NOT a Concept. Concepts should suggest a role the pokemon will play in the metagame. This thread is not for people to get an early jump on cool typing suggestions.
The suggestion of a non-uber pokemon with a rain-inducing effect, "The Abomasnow of the Seas?", sounds like a good idea, as well as being sufficiently vague.
It would certainly increase the viability of a fair few pokes in OU, including a certain sidelined pre-evo of Manaphy!
Reworded my two idea with more info.
Concept: Armor Break
Description: A Pokemon designed to cut through opposing Pokemon's defensive stats via an ability. It can be either through abuse of critical hit moves or some rare ability that cut opponent's defenses in half when striking. If the latter is suggested then it's offensive stat would be average to low to offset the piercing.
Concept: Reversal of Worlds
Description: A Pokemon with an ability that reverse the effect of Status affections (I.E Burn would heal 1/8 health and increase attack by half).The main idea behind this is to great status sponge and to punish the status user for his/her abuse of it. This also work on stat upper/lowers (I.E Sword Dance would lower it's attack by -2)
In my opinion I actually like it to work on Status ailments only, but the stat buff could easily be added into an ability like that. For the status...I can think of four status that could work with it. The others seem tougher to say.The Reversal of Worlds looks pretty nice. But I think it should just reverse the effect of status instead of stat uppers/lowers. And one more thing, how would it reverse paralysis/confusion/attract etc. It could be something like it throws the status back at them (like synchronize) but it doesn't get hit by the status.
