Alright, started the game, got Jolteon, Teddiursa, yadda yadda, caught Gullpin and Spheal and my challenge begun. Purified them with a combination of Mt. Battle, Agate Village and random Cipher Peons. Killed Shadow Carvanha by accident, skipped the rest of the Hexagon Brothers, and caught Spinarak. Completely screwed up and killed Numel. Crap. On my way to purify Spinarak now, just got the bar down to the end.

Notes:
Try to capture EVERYTHING I can, so as not to overload Miror B. with Pokemon. Gotta get my Numel from him, anyhow.
By the by, I am playing without a memory card, so I can't save and I'm just letting the game run. So I can't just reset for that Numel.
