It isn't that necessarily dislike seeing Jitte in any particular matchups, but rather they don't do as much as I'd like compared to the current maindeck configuration. As it is the maindeck works very fluently in essentially all aspects of its gameplan; early acceleration, disruption, card advantage, etc. By adding Jitte into the maindeck, regardless of what you're cutting, some part of that becomes unbalanced, which I found I didn't like. The aggro matchup may improve a bit, but the control matchup may go down a little. There was some inconsistencies to my gameplan while running Jitte maindeck and it occasionally interfered with the deck's game 1 engine, where Sylvan Messenger is at its best. It just wasn't a good fit for me personally as I have a particular playstyle with the deck, and I've felt it's done better for me if I have the option to bring it in matchups where I know I'm going to want to see it as opposed to drawing it when I won't want to.
