This has been my go-to Gauntlet deck for about 4 months. I get 7 wins on master about 4 out of 5 times.
The deck is pretty self-explanatory. It is very consistent. It relies on a lot of lifegain to avoid getting run over by aggro. And it has a lot of aspects that the AI is bad at (especially Bartholo and battle tricks).
Let me know if you have questions.
