Why lasts the Abyssal Curses only 2 turns, while Curse of Rafaam can remain forever?
I know, the Abyssal Curses increase the damage for the new ones, but I LOVE Curses.
I’m playing a Excavate Curselock, it’s pretty nice.
It’s the only deck I know, where I can play bad cards, like Curse of Flesh and Commander Ulthok for lethal range.
So, my wish is, remove the “2 turns” and make it forever, like Curse of Rafaam. 
I really hope, we’ll see new Curses in the future, like Curse of Tongues.
