Sigh, even during the violent storms in the CAP discussions, I still support Drought. Gosh, if we don't take this chance NOW, there won't be any second chance because everyone will moan "Nooo, another weather starter! Dammit!" ad libitum.
I simply don't get why everybody keeps opposing Drought. Tell me why! Your arguments still don't convince me! Dethrone Ninetales? Please, even if it was so I don't see the problem. How many Fire abusers in OU do you count? Ninetales for starting the weather, Venusaur for its combo Chlorophyll-Growth-Solarbeam, Volcarona and Heatran for their Fire STABs, and... and who? Maybe Mollux for opposing water? Tell me other sun abusers that might alter the whole metagame. I dare you!
On the other side Rain and Sand are so easily abused that we were forced to ban Drizzle-Swift Swim and Garchomp-Excadrill due to game-breaking. Chlorophyll abusers are all Grass-type Pokemon weak to Fire! And what does Sun do? Increase the power of Fire attacks, so opposing Fire and Ice moves annihilate our Chlorophyll abusers. What is so game-breaking?
And flavor-wise... what can shine more than a sunny day?
Unreleased DW Drought is simply dumb. Or is released with limitations of moveset, or otherwise is almost as useless as Illuminate. A great way to troll everybody.
If you really can't accept Drought, then why don't we backtrack a little to see what was our goal? This CAP is meant to oppose Water...
I thought about that and I wonder... it is possible to give some original ability? I thought to a Water variant of Heatproof (*cough*Waterproof*cough*). An ability like that will be ALWAYS surpassed by Dry Skin (since you want the water healing sooo badly) and at the same time can guarantee a use in a Sun team, overruling its weakness to Water attacks while still receiving damage.
Tangled Feet... this is a snail, it hasn't any feet!
Status immunities sound a bit weird to me. Paralysis is mostly used to stop fast sweepers, but Mollux is quite slow. Ok, paralysis may prevent Mollux to attack once in a while, but otherwise I don't see much use. Sleep status has a major chance to appear due to Spore, Sleep Powder and to an extent Hypnosis, but still doesn't convince me. Breloom and Venusaur for example are scared of Mollux's Fire attacks, while Hypnosis rely too much in luck.
Weak Armor sounds decent and allow a Speed increase, but the Defense drop sucks. Still, sounds good to me.
Color Change could work if it modify only one of its typing.
Another Ability that I propose is Sturdy. It has a freaking shell, it can hide in it! And with Sand and hazards lurking in the metagame the CAP is going to have some problems switching in and exploiting its ability. Or maybe Shell Armor, or Flame Body. Like I said in a previous post, despite Volcarona and Heatran not having any external flame they have both access to Flame Body. Why can't Mollux? Maybe its shell is so hot that whoever touch it risks some nasty burns...
I also love Suction Cups. If this thing gets Shell Smash... eheheh, so scary!
Last ability that I find interesting is Shed Skin. It allows to shrug off Paralysis and Sleep once in a while. Maybe that doesn't make much sense, but also an Illuminate-less Ampharos doesn't make sense since it has a "tail that shine so brightly that can be seen even from space". *shrugs*
P.S.: forgive any spelling and grammar error, English is not my first language.
