13/13s:
Elektra
Nova
Sam Wilson
Wasp
Obviously Nova from that group. But then what? Especially considering my 12/13s:
Drax
Peggy Carter
Professor X
Quake
Winter Soldier
Do I whale Peggy?
I wouldn’t whale her unless you get that extra cover for her. So you could always keep a 120 CP buffer when opening tokens. That would give you the flexibility to buy the 13th cover if you get one you can use.
She is good but won’t change your life with all the 4*s you already have champed.
