Online disabled for Randomizer?

[Dragonstrike]

It might seem minor, but the legality checker for Nintendo's online services does the exact same thing.  Though I know those ones are rather lax when it comes to the type of pokeball the pokemon is in...

Anyways, the point of the legality checks is so only pokemon that are possible to obtain through normal gameplay are allowed online.  And a few of the ways to check that are:
-various values of hidden ids
-the location and level the pokemon was caught at
-the pokemon's stats, moveset, and ability
-the pokeball the pokemon is in (ex: Urayne can only be in a Nuclear Ball, period)
-if the pokemon has a nickname when it shouldn't (this check really only applies to event pokemon, though)

There might be other identifiers, but those are the main ways to check a pokemon's legality that I know off the top of my head.  And randomizers throw ALL of those rules out of the window.  There's really no way to make reasonable exceptions to those checks without giving hackers leeway to do whatever the heck they like with what they trade and battle with online
