What Pokémon are you battling with

The only reason I have almost 200 hundred shiny

I found a level 21 Shiny Magikarp the other day. I’m gonna EV train it and have it hold an everstone so I can have a troll level 100 Magikarp 😂

Late to the party, but Cufant and Copperajah are very easy to isolate (aside from the odd Lucario+Riolu family) in the uppervalley of the North Area running south of the Beads of Ruin altar.
