They're making good use of electric terrain, but I wonder if they'll become too dependant on it. It irks me a lil, as I've never been a big fan of using the terrain moves (it feels like you're just ignoring a big chuck of the battle dynamic) but I understand it's a strong strat, especially as they're nuzlockeing.
@ZEL because he said "rock smash the araquanid because it's supereffective and then thunderpunch for the defense drop" I think he just said the effects in the wrong order, but the others kinda jumped on it lol
