All Stars + Skeelz with Striker and Xingshu as main cards
Pussycats + Skeelz with Sera M1 and Xingshu as main cards
I want to buy two of this clans
I just wish I could afford the 3 of them
You could use PC and splash Xingshu. And if you did that I don't see why you couldn't use Sera M1 and Xingshu. It's true they don't mix very well but you won't always draw both and, if you do, it won't be VERY hard to win with Sera M1 in the 2nd or 3rd round. Or really freak them out and win with Xingshu in the 2nd round. Oops, life gap 7 and you still have Sera M1.
And of course since you're using PC it won't be too hard to accommodate the two big-dogs. Plenty of low stars like Lucy, Nabrissa, Noemi, Jayzel... hmm I think that adds up to 19* so then maybe Cherry/Betty or even Malicia/Ella.
