Play as Inferno.

There are so many things to consider here that it could keep you up for several nights. Right now, I'm playing against someone, late-game Demon versus Haven, and I have to say, it's such a game where luck plays a huge role, like poker. If you're unlucky, you'll be crushed, but if you're lucky, you'll win without any problems. A surprise attack is a skill that allows you to teleport a stack and significantly increase its initiative.
