I find that Teepee hollow or Camp has the best drop rates of them, but even then, they are exceptionally rare, and even harder to collect 5 of the same type in any reasonable amount of time.

Even trying to get 5 of the same type of special from the special grab is annoyingly difficult. it would be better if you could just choose the ones you wanted to buy, even if they were slightly more expensive.
