>>18956445defeatist is unambiguously bad, but archeops can still be very good.
I'm going to fuck up the formatting but I like something like:
Archeops @ choice band
252 Attack 252 Spd
Earthquake
Stone Edge
Knock Off
U-Turn
choice band u-turn coming off 140 attack is no joke. I don't run a flying move because archeops being in obviously threatens a flying move and forces a switch.
You just have to consider him to be a mon who can't be hit at all. Only thing he really needs is good rapid spin/defog support to make sure that he doesn't take too much entry hazard damage.
