Since this is the second straight hack where I did that, I'm now getting annoyed at this mechanic that carried over from the official games.

I held off on evolving everyone until they learned their best moves. Things turned around once my Dratini finally evolved. I spammed Calm Mind, he spammed Calm Mind, but my attacks were nothing compared to Draco Meteor. I couldn't knock it out as Alakazam's only attacking moves were Psychic and Future Sight (I know I should've got Shadow Ball on it). I got into a long 1-on-1 at one point with my Alakazam and this beast. However, this Mega Latias was a real bitch to take down. Blaine had a Mega Charizard Y with the same treatment, Drought taking effect immediately, so I was a bit used to that. Oh yeah, these E4 members and the Champion have Mega Evolved mons right out the gate, they don't have a mega evolution turn. Lorelei and Bruno were around my levels or I was slightly overleveled, I was a bit underleveled against Agatha, then Lance was even higher with a level 68 or so Mega Latias that kept sweeping my team.

Other gym leaders didn't have that kind of spike in levels, so clearly this final Giovanni battle was touched up to be more difficult. For context, my team was in the high 40s and low 50s, while he had a mon or two at level 60. Then the Giovanni gym battle suddenly had some surprisingly high-level mons. Most of the game is pretty smooth, not difficult, didn't need to grind. There's also a bit of a difficulty spike at the tail end of the game. Whatever the case, interesting features in the game besides the obvious sprite replacement: Mega Evolution, physical/special split, Gen 4+ moves and abilities, and mons that span Gen 1-5 (at least as far as I've seen). I never played a Moemon hack before, so perhaps I started with the best of the bunch already. The official thread for this hack mentions that it's the most advanced Moemon hack. The squad's movesets, stats, and abilities.
