I had both of those at 2 in my early budget builds because I rolled multiple of them too. Ping at 2 sort of comes up if your first one dies and you need to remake one to tutor again and Atypus at 2 is really funny because not only does her attack boost stack but her negate and pop is only a soft once per turn but I've only summoned two Atypus once in a whole year.
If you're experimenting with different engines that can get two level 4s on field without using up your normal summon you'll burn the first Ping to tutor a traptrix card and to make Sera and then can use the second one on your actual end board.
I'd keep the second Ping.
