I think the AI will be decent, but not amazing with the deck I've drafted. My deck is consistent; I don't have many broken draws in exchange for many keepable hands that do the same thing every game.
The funny thing is I suspect my deck will be hard for some human players to pilot correctly. There are a *lot* of interactions and decisions that are not obvious at first glance. Sometimes you want to put all your Merfolk into play and sometimes you want sit back on
Library of Alexandria to draw a bunch of cards (this is usually the right choice unless you have Finkel in play). This probably does not bode well for my tournament results. I am OK with this because the deck does some cool things... in one practice game I managed to outrace turn 4
Progenitus. In my other games I was less foolish and simply made sure I could counter the turn 4
Progenitus.
