Hello, me and my friend were playing duos he was on the new hero Jim Raynor. And he had 2 Karmic Chameleons. As soon as the chameleons transformed into the battlecruiser both me and him could see the upgrades displayed in the enemy warband. After the fight ended we both got those upgrades in our shop. I had frozen Eyes spell before that. Which after the fight got removed. I would guess the upgrades moved the whole shop from left to right by 2 cards.
