Pokerus and Natu/Xatu (stored power & roost)

I'm in need of a natu/xatu to breed a sigilyph that knows stored power.
I would prefer a male natu/xatu that already knows stored power and roost.
Also I need any pokemon that is STILL infected with pokerus.

I have a few dream world pokemon like taillow, gastly, tangela, misdrevus, and a houndour.
*All male except houndour

I have a few other pokemon, but thats about it

Thanks for replies!
