All pokemon in the no-eggs group, with the sole exceptions of Nidorina and Nidoqueen, should be banned from all online and tournament play since everyone who uses them is a cheater. For the same reason, though to a lesser extent, Hidden Power should face the same restrictions.

And no, you didn't catch that max IV Heatran with HP Ice. You didn't even RNG or soft reset to get it. You made it in Pokesav in less than five minutes. Don't even try to claim that it's legitimate just because it passes the legality checker. Cheating is still cheating even if you don't get caught.

Pic related; he's as legit as your competitive legendaries.
