Alrighty, here goes.
Somepony attacks. then you make up a way to counter attack it or deflect it in any way, shape or form (nothing profane) to attack and optinally hit that person with their own attack. then, you attack the next pony (the one who counteracts your attack).
Wash, Rinse, Repeat.
Example:
Pony 1:
Missile launch!
Pony 2:
Pyro's Airblast :3
Falcon punch!
Pony 3:
*Blocks and crushes fist*
Fire Wave!
So on, so forth.
(Plleeease let thisbe a good one :S)
Let's begin.
Tomahawk!
