Ciel is so versatile in her Movepool that one wonders how she was able to be available in OU for at least a few weeks. Luckily, FGO Smogon realized this mistake and she received the Ban Hammer. Now Ciel is in Ubers, where she is beginning her campaign to replace several Servants that filled the same role that Ciel had in OU.
I thought it was common knowledge on how forced hand shuffle works? I've played with shuffle decks before for teams and bb a few times when the boss is easy. Also if you switch the character with the same one on support their cards stay the same in hand but that'll break a bb lock and reset card
I thought the same, but ive had Ruler Artoria and SBB for nearly my whole account. If you don't have one of those servants the mechanics are probably a lot less clear
About deck shuffling or not, is it not obvious? Ciel skill apply debuff on other teammates -> deck changes so it's new deck now -> 5 ciel cards taken -> debuff removed so we have new deck again. It's same with upgraded bunny skill, it apply buff which change deck. If deck changes then it will be "shuffled", it's nothing new.
