Demon Hunter WTF?

So I have been playing trying to get past the first level to unlock the demon hunter, how far along do I need to be I keep getting my butt handed to me…

Gotta win the whole thing. Keep trying you’ll get it.

Maybe watch a YouTuber or streamer if you feel totally stuck.

You are losing against the DH Prologue bosses…?

The game literally give you rigged draws of specific cards so you can win easily. Where you are having trouble?
