Action

Also lets you play the card or activate the ability in an open Showdown, including on your opponent's turn. Its normal timing still works.

Action alone does not let you respond to a spell or ability waiting on the chain.

Each Repeat cost can be paid only once. Make choices for both executions when playing, not after seeing the first result. The card is still played only once.
