He won't live 2 hydro pumps or 2 tri attacks.
Very much doubt that it'll live through even one.
Porygon-z has amazing coverage but it doesn't have enough speed to compliment that.
I don't think its coverage is actually that good. Sure, you hit everything neutrally, but only seven types super-effectively, and most of the time Tri Attack is the superior move anyway.
One of the reasons they're so effective is the fact that a lot of peole just don't run Fighting-types. RU is filled with physically defensive cores and Fighting resists like Uxie and Gligar, not to mention the bulky spinblockers like Cofagrigus and Dusknoir. Of course, that brings in the second reason they're effective, most cores are designed to handle physical threats so specially offensive threats like Pedo, P-Z, and Moltres absolutely rip through weakened teams.
