Ingenuity counter

Ingenuity counters are a type of counter introduced in Dominaria United. They act as a counter for an ability to cast artifacts without their mana cost.
==Description==
Ingenuity counters first appeared on <c>Jhoira, Ageless Innovator</c> in Dominaria United. Jhoira has an activated ability to add two Ingenuity counters to itself which then allows the free casting of an artifact from the player's hand with a mana value less than or equal to the number of cards on it. They represent the artificer's ability for innovating and creating the artifacts.
