The returnee-exclusive Epic Exchange Ticket this time is

You can exchange it for one of these. I don't have many of the characters, so I can't confidently recommend one. Out of the ones I've used frequently, it's the 4th character. My review is... "Pick them if you're building a blind deck." I haven't unlocked Last Word yet, but... For the regular spell cards, they all "inflict 3 stacks of Blind on the target upon use." It's also important whether they can break through status-inflicted barriers, and... The single-target skill "Pink or Not Pink" can break the blind barrier with 1 boost, while the AoE skill "School Trial" can break it even without a boost.
