Hit chance

Hit chance

This card Discovers an unknown number of times, but at least 1. The displayed value is a lower bound. Single-Discover hit chance = 3 ÷ 54 For d Discovers: hit chance = 1 − (1 − 3 ÷ 54) ^ d, where d ≥ 1 Therefore, hit chance ≥ 5.56% A card cannot appear twice in the same Discover, but it can appear again in a later Discover.
