Uranus works the same just as Griffin, so you don't need to pay much attenttion to her since GSR Griffin's max skill is 350% dmg to all enemies 25% chance and if you only have SR Uranus max skill her dmg is 350% dmg too but her activate rate is 20% only. She'll be useful in Alliance Battle, campaign and duels though so you can build her, but there'll always be better cards.

Imo Griffin as an attacker for archwitches will be enough since she is a GSR, but soon maybe you'll want to switch her with other attackers but it depends since fantasy archwitches have minions and your Griffin can kill them in one shot with buff/awoken burst and you can focus on killing the fantasy archwitch without disturbance if your team is weak.
