Gabriel is one of them (a good buffer) and Atalanta is another (self buffer, comes with C-Frame defense debuff). it's free pulls so why not give it shot (plus you still have a long time before the crossover event ends so it's not too much of a rush).
consider getting miracle tickets when you can so you can instantly get some strong water SSR like Cthulhu without having to deal with random luck.
