Makes sense. I have it in my Nekusar deck, and have had similar worries about it. However, my main objective when I created my build was speedy games. Whether I'm the victor or not. Haha. I got tired of 4-5 player games in my meta taking 1-1/2 to 2 hours each.

Ah yes for a quicker Nekusar kill I could see that being a great card. Mine tends to take its time, build up some walls on my fort, counter things that might break my build up or compromise my fort, and then hold up counters for after Nekusar is out with one of the 2 auras that will mess with my opponents' hands. ;) So I guess mine is a slower and more control-ish Nekusar build.

Added in Crumbling Sanctuary as I am an evil sonofabitch lol.
