For starters, Archeops is by no means a great Pokemon. It’s Deafeatist ability holds it back by cutting both offensive stats in half when at 50% hp or lower. But, we can negate this with a sitrus berry. If Archeops’ hp drops below half and goes back to over half from the sitrus berry, we can enable it to keep hitting harder. Acrobatics is especially useful since after consumption of the berry, we are above half hp and have a 110 power STAB flying move going off of our regained 140 base attack. Roost is a secondary option for Archeops as in some situations you may want more recovery and the ability to hit hard for longer. Rock slide helps check Flying, Ice, Fire, and Bug types. Rock slide is also a STAB move that does great damage while having a high flinch chance to pair with its decent 110 speed tier. Earthquake is great for Steel, Fire, Rock, and Electric types. U-turn enables Archeops to deal great chip damage and safely pivot into a partner. Archeops does massive damage when it has a good position with its nice coverage.
