Suggested by Destroyer Bishop is a strong hero so you never want to count him out of a fight too quickly but he’s not going to be able to hold his own against the Grave Joker for very long. Grave Joker has better attack options at his disposal and is also quick enough to dodge Bishop’s counter blows. At that point Bishop’s only hope is to try and move quickly enough to land his own hits but he just won’t be powerful enough to win this fight. Grave Joker wins.
