Optional effect
Optional effects are effects that a player can choose whether or not to activate. Optional effects include the phrase "You can" in their card text.
Missing the timing[edit]
Optional effects that use the word "When" can miss the timing. Optional effects that use other timing words, such as "If", cannot.
Mechanics[edit]
When multiple effects trigger at the same time, they are all placed on a Chain, with the mandatory effects being activated first, followed by the turn player's optional effects and then the non-turn player's optional effects.
