I'm an idiot.
Porygon looks really scary. Z-Conversion gives it +1 to every stat! Combined with Download it can tear things up.
It's a lot more fragile since no Eviolite and it needs to run Timid and max speed, but it's also a lot harder to deal with it since it's counters are dependent on whatever it converted to and on which coverage move it doesn't have.
