So Archeops vs. Carracosta. Teach Archeops Hidden Power (Grass) and it'll do 3x damage to Carracosta due to Rock Solid ability or if it has Sturdy 4x damage. Btw if you're going to use aqua jet, Archeops has quick guard and perhaps breed it roost so it can recover its hp. Endeavor is quite useful in this case, if Archeops survives, however. Although Carracosta definitely looks cooler and has better abilities/ defense.
