I think Oath will always be a good choice for Vintage. I hadn't played in four months and went 4-1 in league with it. I also played it in a challenge this weekend and went 3-3. I couldn't say that I was disappointed with the decks performance, or that it wasn't a good choice to play.
I have some ideas for the deck in the current meta, so I will test them out. If I find something that works well and put up results, I will post the deck and write about it. I should also be streaming within the next couple weeks, so once I get that going you can count on seeing Oath getting played.
Also, if you have any questions about playing the deck you can message me or make a post and someone will answer.
