I play Raffaele on every attack (diamond) with Vivica (no costume) since I got him. He is roughly as strong as standard Vivica. In detail, he is a little bit weaker because Vivicas shield outperforms Raffaeles high defense (and other smaller traits) on average.
Raffaele replaced Marie-Therese as second healer for me. Marie is significantly weaker and maybe only usable in 5* bonus tourney without yellow color. She synergizes with Snow White. I also tried Anzogh, but he feels like a mediocre TC hero on attack.
