Probabilities to assemble A and B on turn T
A combo deck often needs to assemble two cards: A and B. The easiness with which a deck assembles A and B is a sign a stability. It is then important to determine this probability using the hypergeometric distribution (article to come) with multiple variables. Each group consists of cards that are part of the combo or that can fetch them.
For example, for Kinnan, Bonder Prodigy, group A could be made of Basalt Monolith and cards like Fabricate or Trophy Mage and group B could be made of Thrasios, Triton Hero, and cards like Urza, Lord High Artificer or Chord of Calling.
