Schedule for 5-star Heroes for Hire?
It's been asked before, but I've learned not to open up a thread that hasn't been posted in for over a month. Is there a schedule for which 5-star Hero for Hire (character and cover) will be available in future events? My 5/4/3 Black Widow is very curious when I can get her 13th cover. My 5/5/2 Thanos is curious, but ready to wait a long, long time.
