Same here. I just trade for dressbloom for 500...and it was still available. However when I trade for lower cost dressbloom, it was disappeared. I guess it would a good time for people whom didn't get their 1st Edelweiss maxed out to get done now...before the system goes under maintenance and error gets fixed.

I managed to finish the last stage of 2nd phase pretty easily. Just make sure that you have 3 of fast team like 600-700 speed on top, 1 team of 400 in middle, and 1 team of 500 on bottom.
