Coalition Honor Guard

Creature - Human Flagbearer 2/4, 3W (4)
Whenever a spell or ability an opponent controls is put onto the stack, if that spell or ability could target a Flagbearer in play but doesn't, that opponent changes one of its targets to a Flagbearer.¹
Giving little thought to their own defense, they carried the flag that united their army.
Illus. Eric Peterson

Crystal Keep Rulings Summaries

• The requirement to choose a Flagbearer as a target only affects the choice of targets. It does not affect the check made for legal targets when a spell or ability resolves. So having a Flagbearer enter play after targets are chosen will not cause a spell to be countered. [Barclay 2001/07/09]
• Note - This card was creature type "Flagbearer" until Oracle 2007/10/01, when it became "Human Flagbearer".
