Shelmet's evolution Accelgor looks a bit peeved, standing with his arms crossed and his head down. It's no wonder, because his defensive armor has been stolen by a sneaky Karrablast/Escavalierduring a trade. That's why the Shelmet/Accelgor loses armor with evolution and Karrablast/Escavalier gains armor, and that armor swap is the catalyst for evolution when you trade one for the other.
