Hidden Blooks are treated here as a taxonomy explainer topic. We avoid making acquisition claims that are not represented in the indexed pack data.
Why Hidden Blooks need a careful explanation
Hidden Blooks generate a lot of curiosity and a lot of bad information. The safest, most useful way to handle the topic is to separate collector taxonomy from pack math. Hidden Blooks may matter in community discussions, but they are not something this calculator can responsibly model as a normal pack chase.
