Here's a strategy for all those rookies who are desperatly trying to get
their Coalition Flag onto their opponent's creatures.  You might have to go a
bit old school, since I don't believe Coalition Flag's best friend is Type II

Coalition Flag (Apocalypse)
Enchant Creature
Coalition Flag can enchant only a creature you control.
Enchanted creature's type is Flagbearer.
If an opponent plays a spell or ability that could target a Flagbearer in
play, that player chooses at least one Flagbearer as a target.

Ray of Command (Mirage)
Untap target creature an opponent controls and gain control of it until end
of turn.  That creature is uneffected by summoning sickness this turn.  Tap
the creature if you lose control of it at the end of turn.

The combo is fairly simple.  Play Ray of Command to steal opponet's creature,
while he's over playing on your side of the board, throw the Coalition Flag
on him.  Send him back home at the end of turn. Enjoy.
