Modest Nature

This core is just about always able to break through teams and this case is no exception. Though this team does have priority which can usually stop Xern after it sets up, if you setup on waterceus and either trap or chip pdon (also hit the fmiss on steelceus which is about a 9% chance to happen) then the game will end
some side notes
- 148 speed xern at +2 outspeeds scarf mray
- dug can also trap the steelceus i guess but it's a speed tie so l o l
- even if this fails and you're not able to trap pdon, geo xern is still a massive threat to the team and can take out multiple mons
