I take it that if you pack six Continuum Knights in a deck, if that sixth dies (Fractal/Mitosis shenanigans notwithstanding), that's it, right?
Consider the situation when one brings three unupped CK and three upped CK in the same deck. The first one to hit the field, an unupped one, died from a stray arrow from Eagle's Eye. Which one is brought into the field: another unupped one, an upped one, whatever's topmost, or randomly?
