The problem with e. tutor is that obviously your best target is oath of druids (unless you have vault or key already) and a lot of times you don't really want oath, since it doesn't effect the board when it hits play, and if they don't have a creature or you don't have an orchard it does stone cold nothing. I think that the best oath list is one that minimizes dead draws since it already has quite a few of them, not increasing them. In addition, if oath is what you want, and you use e. tutor to get it, and then your oath gets countered you are so far behind. People have been cutting mystical tutor for this reason, and that gets (in my opinion) much stronger cards.
That's a fair assement of E Tutor. Like I mentioned in the artilce, I wasn't 100% sure on the card, but I was looking to streamline the list and wanted to go outside the box. Plus I like the utility it provides postboard in some of the matchups. I could easily see the E Tutors cut to add some combination of the following cards: Jace, Preordain, Gifts, Regrowth, or even some more counters.
