Appendix IV

Some Deck Math

MULLIGAN CHANCE BY NUMBER OF BASIC POKÉMON IN DECK

Below is a breakdown of the percent chance your deck has of a mulligan based on the number of Basic Pokémon you’ve included in your deck. As the number of Basic Pokémon increases, the percent chance for a mulligan decreases. It is necessary to weigh the chance of a mulligan against other factors, like consistency. If you include a lot of Basic Pokémon to avoid a mulligan, it could cut into your deck’s ability to draw the cards it needs.
