Contrary pokemon are rare when laying good opposition, and not really a significant threat until very late game vs a good team
Water spout + specs palkia wouldnt work very well (i tried it ;) Water spout doesnt do enough even with modest nature in rain (38.9% - 45.8% to giratina)
Now running that swift swim + tail glow + water spout might be interesting, but slaking espeeds would do enough to make water spout mediocre.
