What's Your Ideal World Series Matchup With The 4 Remaining?

I should go Astros-Nats. Montreal/Washington has never even been to the Series. But I still have a soft spot for the Birds on the Bat. Don't want to see the Yankees in it. I was kind of full of myself after the Sox 2018 Blitzkrieg. I'm already getting some payback and it will triple from the Yank fans if they win it all.
