Triggered effects may be optional or mandatory. Optional triggered effects will be designated
with a “may” or similar wording, while mandatory triggered effects simply describe the outcome
without giving a choice. Mandatory triggered effects that are not negated persist at least until the
end of the current phase, even if the card leaves play or set aside, unless otherwise specified on
the card. If the triggering event deactivates the ability without interrupting or negating it, then the
triggered effect can still be activated. If the triggering event activates the ability, then the
triggered effect can still be activated. Otherwise, optional triggered effects may only be activated
while the card it is on is controlled by the holder and is either in play, Land of Redemption or
set-aside area
