Next time you are at the enemy flag and you are alone (no resistance) pick up their flag, drop, pickup , drop as fast as you can. Most time it will duplicate into 2 flags. Also works if you are stuck in a hunter ice trap at their flag. When it does dupe, once someone picks it up, there will still be a second flag there for your team to grab.
Again, spam the drop and pickup as fast as you can. (right click the flag 'buff' to drop)
