📐 Consistency Rules

Type share

Track how much of the main deck is monsters, spells, traps, and flex.

share = category copies / main deck size

Starter access formula

Use the hypergeometric distribution to measure starter access in the opening window.

P(X = k) = C(K,k) C(N-K,n-k) / C(N,n)

Two-card line

Check lines that need both a starter-side card and an extender-side card.

P(A and B) = 1 - P(no A) - P(no B) + P(no A and no B)

Target copies

Scan upward until the desired consistency chance is reached for the chosen seen cards.

needed copies = smallest count that meets the goal

Counting rule

Count each card in one primary bucket. That keeps the hypergeometric opener math exact and makes the consistency score easier to read.

Reading the result

If starter odds are short, add starters first. If starter odds are fine but your combo line is weak, push extenders or interaction before adding more bricks.

Klasike the proportion was 20 monsters 10 spells and 10 traps, where mantrapo-cards kalkuliĝas as monsters. For covers above 40 the extra cards should follow 2:1:1. Even so it alters according to the cover and the ludstilo.

Use more monsters and spells for arketipoj as Fusion while others stressed traps. Some players favour 1:2 of spells-traps to monsters because it operates more well.

Building think whether it will be to control or comb. Kontrol-cover requires cards that searches the mainstream monitor. Exterior kampa spell helps to set the revolution.
