Really the only strategy I can come up with for doing this portion of the event short of spending a crazy amount of money on puddings is to convince low level players who haven't managed to level their guards at all to funnel them in to you, that of course requires you to ditch your carefully groomed friends list in order to pick up a bunch of players that probably won't stick around. And even then, if the super guards are strong enough from the onset, it might not make it all that achievable. I don't know how powerful they are at levels close to 1.
