Just posted, this weekend’s upcoming release is Valkyrie (Asgardian Warrior) from Thor: Ragnarok.
She will debut in the Simulator story event and be the essential in Thick as Thieves which runs right after that. Her lone active ability is her red, which is a damage ability that can dip multiple times on strike tiles. Her passives are a mix of AP creation/denial along with strike tile creation (which would go great with her red).
In addition to the story events she is included in, her versus event “Scrapper 142” will begin on March 25th as well.
