While an opponent is choosing targets as part of casting a spell they control or activating an ability
they control, that player must choose at least one Flagbearer on the battlefield if able.
Whenever a Flagbearer you control becomes the
target of a spell or ability, you may copy that
spell or ability. If you do, you may choose new
targets for both. At least one of the targets must
be a Flagbearer you control.
