Who wants to be my first?
I challenge anybody to a 2v2
The arena you ask?
How about an abandoned cellar. Rusty chains hang from the ceiling and shattered glass litters the floor. Pokemon who need to stand on the ground take a small amount of damage from the broken glass each round. Those Pokemon that can fly/levitate or hang from the chains in the ceiling will have an advantage here.
Who is up to the task?
