HsReconnectTool VS Hearthstone_Battlegrounds_Skip

If you are talking about skipping the actual battles in Battlegrounds then the HS Reconnect Tool is an easy way to accomplish what you are looking for. It is open source, so you can see what you are running, and verify that there is no malicious code in it.

I've found this disconnect tool to be the most effective. Make sure you set the properties to always run as administrator. Creates a firewall rule in Windows Firewall for 4 seconds and then removes it. Works best when you activate it just after the turn timer hits 4 seconds remaining, as it will completely skip loading the battle phase and reconnect you directly to the next buy phase. For whatever reason I've found that running it after the battle phase starts still works, but often breaks Bob's Buddy and sometimes even forces a game restart after finishing the run.
