Third Gen Move-Tutor & B/W

[erebus]

Hi, I'm fairly adept at getting PokeGen-created pokemon to work on B/W Wi-Fi. But I can't seem to get pokemon with Gen-3 moves working. For instance, a perfectly legal set should be:

Dusclops 508 EV, 31 in DEF/HP/SPD IV, a correct ability/nature/gender/PID set (pressure/calm/male), correct location, with a legit movepool:

Night Shade (by level)

Seismic Toss (3rd-Gen)

Trick Room (by TM)

Mimic (3rd-Gen)

Yet this pokemon is rejected by the official server.

I assume it's because one of the following reasons:

-The official server does not actually consider Gen3 moves legal (even though they could easily be) for simplicity's sake

-There's some hidden data that needs to be inserted

So I'd like to ask. Whether it's either of those issues or if I'm missing something else entirely.

Secondly, my goal is to create a legit ExtremeSpeed / Gluttony / Bellydrum Linoone for Wi-Fi. Is this currently possible? Does the official server recognize that set as legal even if you actually obtain such a rare pokemon?

Attached the Duscplos if someone is curious

SID is within bounds but is obviously hacked.

Try checking with a normal moveset, then find out what move is illegal via elimination..

There's nothing really wrong with this pokémon, bar its secret ID and wrong trash bytes. Try to remove the gen3 moves and see it it works. I'd like to know why this gets rejected...
