I'm expecting Rasputin > Seimei > Other things. I won't be rolling if it's either of those two tbh, it's just what's I think it has a higher chance to happen. If it's Proto Merlin though, oh boy, unless they reveal more silhouettes and one of them is either Violet or Kazuradrop.
And I will most likely be skipping summer even if I don't roll anniversary. Even if it has something like Summer Morgan, it just can't beat normal Morgan with a veil.
(I say that but there's a chance one of the Servants is really well done so not a guarantee)
