>>32521213Adding onto what i said, you might want an Ampharos instead of a sleep setter, Twave is more accurate than Noctowl's Hypnosis.
So, here's what an average reset will look like:
>You hit Reset on your GC/Wii that you moved close to where you're sitting>have a party slot open>you run out of the hotel, because that skips the UFO travel animation for leaving the Under Colosseum>you use the R-Disk that you set at the top of your Key Items slot>run up to Venus and start the fight>SurfQuake, and assuming everything goes right, after that Suicune comes out>Switch out one of your pokemon for Ampharos/Noctowl, then Twave/Hypnosis while chucking a Net Ball with the other pokemon>once it's asleep/paralyzed, throw balls with one mon, and weaken it with the weakest attack Ampharos/Noctowl knows>keep doing this until it's caught>after Venus runs away, check your party. The portrait will be in a different pose if shiny, along with the different color>hit resetBest case scenario, you 1shot all 4 pokemon, and instantly catch it, whether you got a lucky Net Ball or cheated in a Master. My estimate for this all is 5-6 minutes. My fastest Ttar reset took 4:35.
