If you would like to vote for a specific coordi gacha to appear on the rotation then head on over here and vote:
As you know the poll will last a week and the top four winning Gachas (with one being AP which will be selected by us) will be rotated soon after the poll ends.
After the poll closes, an announcement will be made with the list of winning Gachas that being Armor and Coordi. Vote as soon as possible as all votes matter!
You can preview some if not all of the gacha sets in the page below (We suggest you View Albums for better results):
