grass -citrine mountain, you enter from the left side of Celestine cascade
electric- on top of Devin corp
Dragon - apophyl cave
ground - ?
dark - where sableye was in iola valley
dragoniumZ- behind Mirage tower is a stair case which leads to a lemonade stand and there is alolan eggy there in a basket (lol) and its in the basket
lets take bulldoze up a notch,
i ran max hp, some spdef ferrothorn with bulldoze>tectonic rage to destroy magnezones who think they can stay in and hp fire me
ultra gimmick since i just live the hp fire
The most recent one I found was with the item finder in tourmaline desert, where the mirage tower is supposed to be there are some ladders and its on one but keep in mind a hidden item it is
I just threw a pokesnax in the circle thing, exited the area, went back, dropped down a hole, it was there and immediate battle start, maybe try exiting the entire area?
This here is an app on playstore and App Store, all famous poketubers are on it, and has literally become the new pokecommunity. It would be great to see reborn on it too
