Lol definitely understandable, in that way, we'd have to be realistic about it. Even down to physics. Like some random example:
"Scyther quickly brought up its arm readying for a slicing motion on the Snorlax, running closer it jumped into the air and brought its arm down intending to use cut on its stomach."
^then the next person would post.
However, because it is a snorlax in this case, the Snorlax couldn't all of a sudden dodge it.
Basically posts will be a lot smaller, but quicker, especially if we're both online. Also it will really test one's writing skills, as to see and say where and what the Pokemon is doing exactly, so that the other won't take advantage of that. That is because we write in our own weaknesses (intention and unintentional). Usually these types of combats too, generate more quibbles, because people deem them "unfair", but the case usually is what is written. Though I've noticed you're a good RPer, so I don't see that happening ;)
