Eventually hoping to do some GVG, I'm also hoping to obtain a Champions Retreat for every era. From various sources, I'm seeing that they should be available in special events, rare daily challenges (only 5%, though), and very rare occasions from the Antique Dealer. My google-fu is very lacking this morning, however, and I've been unable to find any good sources that show odds of finding one in Antique Dealer. I'm wondering, too, what the most reliable way to obtain one would be. Has anyone had any regular positive experiences spending diamonds to refresh the Antique Dealer? I don't mind spending a bit, but I'm curious how rare it is there. Any tips or suggestions here would be greatly appreciated.
