Sableye in the Great League
I haven’t seen many people talking about it yet so I think I may start asking. The potential of Sableye in the great league seems to be amazing. Just under 1500 if it’s perfect and maxed, having only one weakness to fairy type and boost several resistances. Not to mention having ghost type attack and also dark type to counter Psychic types.
If it’s all as I predict then I’ll max this one out!

This is why smaller leagues are great in my opinion. A chance for low max CP pokémon to shine. In the current gym defense system, performance does not matter that much but high level, low base stats pokémon tend to perform better than low level, high base stats pokémon... Or it's just a matter of stats distribution maybe. In any case, it gives room for more pokémon in the competition.
Just caught a weather boosted Alolan Raichu yesterday... CP 1525 :'(
