The only relevant nullifying dinos are tanycolagreus and, to a lesser extent, monostegotops. Many people when asked about a monomimus nerf just say “nullifying dinos are a good counter”. I see plenty of 18-20 monomimus daily and you’re going to need about the same level tany to deal with it, which I just can’t do. And monostegotops isnt powerful enough to finish it off before getting distracted. Its immunity definitely doesn’t help, and its speed means that tanycolagreus is essentially the only somewhat reliable counter for it, which is why I’d like a tany hybrid or something decent that can nullify.
