I only took a quick glimpse of it, but I'm fairly certain that bridal Oncidium is the ONLY rainbow in the 5* ticket, which means the 20% figure is for her only.

Edit: Ninja'd.

That said, after the past two 11-rolls gave me two golds each, I should've seen this coming.




As for my ticket, I was fully expecting a gold dupe, but randomly thought, "German Iris would be nice".




... Okay.
