Got all characters in this collab with about 32 k rubies and their special cards...got the set too but no option card at all, don't think I'll pull anymore for them at this point. Kinda salty that none of the characters is a leader for this collab, its imbossible to run them in a single team. We had a leader for Tekken, Samsho, WWE, Gintama but not this that has 5 Fes? Come on...
I imagine a part two of this collab will come at some point that gives us the other three Knights, so that all of the "seven knights" appear in the game. Then one of them can be the 7K leader unit.
