Wait, so you're saying that you would hate to see E-vire come down not because it would be broken (as you said, it probably wouldn't) or centralize the metagame, but because you wouldn't be able to use Raichu anymore. lol.
On another note, I feel that a lot of the stall teams I've been facing on the ladder are relying too much on Milotic against the myriad special Fire attackers. A typical core I've seen goes something like Weezing/Milo/Tomb/Registeel, with Chansey and Venusaur also being popular. With entry hazards and double-switching, Milo can easily get worn down into KO range for, say, +2 Dark Pulse from Houndoom or HP Grass from Moltres. From there, the aforementioned attacker can go on and sweep unperturbed. I would recommend packing another pokemon that can actually hurt fire-types, especially since Milo is being relied on to also wall a whole bunch of other crap. Also, anyone running Subperior should definitely outpace that damn Weezing. Stone Edge 3HKOs, while you can grab a free Sub against something that's supposed to wall you.
