I guess the sensible choice for the first Miracle Ticket will be Cthulhu (Her C Frame Def Debuff is way too tempting) and she has a Raphael'esque Overdrive absorbing skill that doesn't overlap with Ryu-Oh's Overdrive Extension making it two extra turns without getting blasted
This so I use D'Artagnan as my Main and have Both B and A Frame Covered with an extra C Frame Defense for more Damage while the EX Skill will be free for anything the occasion requires (ex: raids that require you to run Chaos Magic or just an extra buff)

And for the Second Miracle Ticket going for Mars which I have planned for a month or so now

Thanks for the suggestion!
