Should I switch Mudsdale out?

nah

This is my last chance to switch Pokémon before Necrozma really as everyone in my party is gonna be too overleveled otherwise. I was thinking since Krokorok and Crookodile are duel ground and dark types, that might be a good switch.

ok
i also recommend using a swagger+foul play combo on necrozma

F**k. I got rid of those moves lmao, this is the first time having a dark type in my party going up against Necrozma tho. I already have Zoroark.

ah

Should I still switch?

idk
