I don't think not being able to do it with one attacker or a team of low level uniques makes it ok to compare it to Ninetales which had only been done by 1 person before gen 3 gave us WF Gyarados.
I was looking at sims in hopes of 1-v-1 soloing it and it definitely does not look easy. Depending on moveset there are a few mons that could pull it off if they're maxed.
