>>58198960I MM'd my moxie Gyarados, Charizard, Tyranitar, and Haxorus all in gen 6 with penta/hexaperfect IVs. Started on Sceptile back then with some really goofy egg moves like grass whistle, synthesis, and leech seed. Never finished that hunt.
Got a second pentaperfect zard in gen 9 that's Timid instead of Modest.
Have you cooked up any EV spreads to see how the megas will fair against the new mons?
