[2019] [Tracker Devs] Advance sample client files

Howdy good folks of /r/MagicArena !

I'm picking up the torch for Charlie here: it's almost release day! In an effort to reduce the scrambling required by anyone who parses our output logs, we're releasing some files that may be helpful in advance. (I'm sorry to say that I forgot to capture a log over the last few days. Hopefully these will help anyways!)
