My friend Casey Carriker (last name may be mispelled) thought of this one. If you use coalition flag to enchant a legendary creature you can have more than one of it. A maximum of 2 of course cause otherwise the flag would go to the first flagbearer legend you made. Also you can make a creature that may be your kill card a flag bearer then give him diplomatic imunity, MM uncommon, which would make it untouchable and would redirect all things that are a potential threat to you or it. Thanks for hearin me and my friend out.
