Is flash getting a shard of kryptonite or a tank of gasoline from wayne manor considred bfr? Assuming the no bfr clause is in effect? Same question applies to a teleporter.
If a speedster is matched up with someone he can't physically beat through punching and kicking, is using his speed to get a gadget that can beat his opponent considered bfr for the speedster?
I can also imagine the battle field area between light speeders and teleporters would be different from two bricks punching each other in a city. The speedsters and porters ( assuming they are powerful enough) can literally make the entire galaxy their battlefield.
If kitty were to fight in new york, and the rule no bfr was implemented, would phasing her opponent straight into the earth's core result in a loss for kitty?
